The darker colored screw is always the hot terminal no matter what,and the other silver or lighter colored are for the traveler pair to the other 3way switch,if the switch and diagram seem to differ,you can go to the manufacturers website and contact them for further info on this question,it could also be the wrong diagram with this particular switch unless its marked identical on both the switch and diagram

It may be easier to note the location of the two screws on the same side of the switch and the single screw on the other side. The single screw on one side of the switch is the pole or common for the switch. Connect the Black or Hot wire to the common terminal on the first switch. Connect the Black wire of the load or lamp wire to the second switch common screw. Wire the neutral (White wire) of the power source to the white wire of the load or lamp. You should have a dedicated Red and White wire which go directly from the first switch to the second. Connect the Red dedicated wire to one of the two screw terminals one side of the first switch. Connect the Black dedicated wire to the remaining screw on the first switch. You should have the Hot Black wire on one side of the first switch and the dedicated Red and Black independently on each of the other side of the first switch. Connect the dedicated Red and Black wires on the other two terminal screws of the second switch. You should have the load or lamp wire on one side of the switch and the dedicated Red and Black on the other two side terminal screws. Do not worry if the Red or Black is on the top or bottom, just make sure the two are on the same side of the switch. Turn the breaker back on and test the switch.

I have an outlet that I want to convert to a light switch and an outlet on the T5625. I can not get the light switch to work. I have a Black hot and neutral with a grond. how do I hook up ht light portion?

Electrical devices have color-coded screws.

Electricians don't guess, they test.
You have tested the wires.

1) Combo switch-outlet device screws are dark - brass - silver - green
Hot to dark
Neutral to silver
Load wire (wire that goes to light, fan, motor) to brass
Bare ground to green screw

2) If you want switch to control the outlet on the combo device.
-Device must have 2 dark screws
-Look at dark screws, there is a break-away fin that connects dark screws.
-Remove break-away fin.
--Now there is one dark screw for the switch part of device, and one dark screw for outlet part.
-Connect Hot to dark-for-switch.
-Run jumper wire from brass screw to dark-for-outlet.
-Neutral to silver
-Switch on combo device will operate outlet on combo device

I have a black/white/ground wire coming from my power supply into my bathroom. I want to install a 274w combination device so as I can have one plug outlet and a switch for the shower fan.I need to see a...

1) In this situation we need to test the wires.
Electricians don't guess, they test, and a diagram would be guessing which wire color does what.

2) FYI: non-GFCI receptacle located in bathroom is not code, and device will have to be replaced when property is sold. The reason for GFCI is the likelihood of you holding defective electrical gizmo from China in one hand while putting other hand in running water. Or electrical gizmo falling into bathtub occupied by wife with large life insurance policy.
If you have kids using that bathroom, I want you to avoid using non-GFCI device.

3) Your new device has color-coded screws: Dark, brass, and silver.
These colors tell electrician how to wire the device.

4) Let's test to see which wire connects to which screw:
Separate wires.
Use ordinary 2-wire tester from hardware store.
Tape tester leads to wood sticks so hands are away from power.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. Hot wire connects to dark-colored screw on device.
Hot wire is identified.
Test Hot wire to all other wires in box, except bare ground wire.
Tester lights up on Neutral wire. Neutral wire connects to silver screw, and will complete circuit to receptacle.
If box does not have a Neutral wire, the circuit to receptacle can be completed using ground wire on silver screw, but I am not recommending that.
Last wire goes to Load (light, fan, motor). Load wire connects to brass screw, and will complete circuit to Load.

2 switches 1 light. replacing 1 switch (very old romex, no ground,but, NOT KNOB & TUBE) lol, with Cooper"s 7503w. The original switch has 4 conductors and Coopers's has 3 and a ground. I checked...

Cooper 7503w is a 3-way switch.
It sounds like you purchased correct switch.
Remember, fixya answers questions about products. We don't sell Cooper wiring devices.

You have a continuity tester which is excellent, because electricians test, they don't guess.
Hopefully you have a voltage tester for testing steps shown below images.
Notice that new switch has 1 dark screw and 2 brass screws.
Dark screw is 'common.'
Brass screws are 'travelers.'
Screws are color-coded so electricians know where to connect wires


If your switch is a 4-way, it will have 4 screws: Notice switch located in middle of 3-way switches has 4 screws.

If old switch is 4-way, then each time switch is flipped, it will reverse travelers on either side of device.
The same is true with a 3-way switch. Each time switch is flipped, the travelers are reversed.
So a 4-way switch can be used as a 3-way switch, so old switch might be 4-way switch substituted for 3-way.

The key is testing wires in your box.
You have two switches that control same light. Switch1 and switch2.
Switch1 is still installed. Move switch1 to DOWN position.
You are replacing switch2 and have unknown wires at that location.
Switch1 is DOWN position.
Separate wires for testing.
Turn power ON.
Test each wire against each other wire and against metal box to find Hot wire with power. Mark this wire.
Move switch 1 to UP position, and test wires again to find Hot wire.
If same wire is Hot each time, then that wire connects to dark-colored screw.
If different wire is Hot each time, then these are the travelers and these wires connect to brass colored screws in either order. The final wire connects to dark screw.

Now if you have additional wire, that could be wire going to next receptacle.
Leave this wire disconnected and check nearby boxes for power.
If this is a power wire that advance power to next receptacle, it probably connects to dark screw.
Again, you should test, and use process of elimination until each wire is identified.

I need the wiring diagram for a Cooper 277W single pole switch with pilot light. The light is to be on when the switch is on. Thanks!

I have 120Volt cooper 277 pilot light switch here in my office.
Dang instruction sheet shows wiring for all kinds of cooper devices.
EXCEPT pilot light switch.

So I tested with multimeter and came up with following:
Key to any wiring device is color of screws.
Hot from breaker box always goes to dark-colored screws.
Neutral always goes to silver-colored screws.
Brass screws are for Hot wires from breaker or Hot going to Load
Green screw - ground

Trying to hook up a pilot light switch to a gfi recp not having much luck with getting it to work properly i got 2 conductors from the panel and 2 conductors going to the gfi recp and on the switch i have...

It is unclear what pilot-light-switch is supposed to turn on-and-off.

Option A) pilot-light-switch is going to turn GFCI on-and-off
Option B) pilot-light-switch is getting power from existing GFCI circuit, and switch controls another Load (light, fan or motor) located elsewhere.

Add a comment at any point.
Bare copper wire always connects to green screw.

1) I have a Cooper pilot-light-switch in my office.
Black Hot wire from breaker always connects to dark-colored screw(s).
White Neutral wire from breaker box connects to silver-colored screw
Wire going to Load (light, fan, motor) connects to brass colored screw.

2) Two things happen when pilot-light-switch turns ON:
a) Pilot light turns on. This circuit is powered by black Hot wire, and circuit is complete with white Neutral.
b) Brass screw that had no power, is now powered.

Hot from breaker always connects to brass-colored Line screw
Neutral from breaker connects to silver-colored screw that is opposite Line screw.
If other switches and plugs are going to be protected by GFCI, they connect to brass Load screw and to silver screw that is opposite Load screw

Option A) You want pilot-light-switch to turn on GFCI receptacle.
a) Wire pilot-light-switch as described above
b) Black wire from GFCI line-screw connects to brass screw on pilot-light-switch.
c) White wire from GFCI silver-screw-opposite-line-screw connects to any white Neutral.

Option B) Pilot-light-switch is getting power from GFCI receptacle AND you want pilot light switch protected by GFCI.
a) Black wire on pilot-light dark screw connects to Load screw on GFCI
b) White wire on pilot-light silver connects to silver screw on GFCI that is opposite Load screw

Option C) same as option B except pilot-light-switch is NOT protected by GFCI.
a) Black wire on pilot-light dark screw connects to Line screw on GFCI or any Hot wire
b) White wire on pilot-light silver connects to silver screw on GFCI that is opposite Load screw or to any Neutral wire

Need a wiring schenatic for 66v

I answer questions for free.
I know electrical wiring.
I have an image of the 66V, but it does not show the screws or color of screws.

I cannot find a manual.
SO, if you can 'add a comment' to this post and tell me the color of screws on each side of switch, I can tell you with 100% certainty where your wires go.

Otherwise I will shoot wild and see if I can hit the target.
1) One side of the switch has dark-colored screws and the other side has brass screws. The Hot black wire from breaker attaches to the dark-colored screws. The wires going to Load (fan, light) attach to 3 brass screws.
2) One side of the switch has brass-colored screws and the other side has silver colored screws. The Hot black wire from breaker attaches to brass screws. The wires going to Load attach to 3 silver screws.

I have a single pole lighted switch with no wiring diagram. it has two screws on one side and three push connection holes, two marked common the other not marked. how do i install it properly?

I hesitate to answer question because the color of the screws is not identified. The holes are not identified which color screw they are next to. You can fill in these blanks when answering if the following information is not complete.

First of all, the green screw goes to bare ground wire and isn't discussed further

Usually a single pole switch has 2 brass-colored screws.
This tells you the wires from old single pole switch can connect to either screw.
Normally the quick-connect holes are located next to a screw >> that screw and the hole are connected. Sometimes there are two holes next to a screw >> and the same rule applies that holes are connected to screws they are next to.

If your switch has two screws and the colors are brass and silver, then that tells you something else.
It says that black-hot-wire-from-breaker connects to brass screw.
And wire-going-to-load (fan, light, motor) connects to silver screw.
If you do not know which wire is which, connect wires, if device doesn't work, then reverse the wires.
Again the quick-connect holes are located next to screw they are connected to.

If your switch has threes screws, then that switch has 2 brass screws and 1 dark screw.
You can wire this device as a single pole by connecting wires to dark screw and either brass screw

Hi I have a 691 and want to outlet on all the time and the switch to control a light. Your diagram show black wires on one side and the white wires on the other side. Shouldn't a black wire be on one of...

If your switch is wired internally so the switch automatically controls the plug, then there is not a way to re-wire the insides of that device.

Look at the screws on your device.
If switch automatically controls the plug, there are probably gold-colored screws on one side of device and silver-colored screws on other side of device.
The blacks connect to gold, the whites to silver

If this is how your device looks, then the switch cannot control a light, so buy a device that looks like the one described next:

If the plug and switch can be wired separately, then the screws are different colors
1) On one side are dark-colored screws. The Hot wire from breaker box always connects to dark-colored screw.
2) On the other side of the device are 1 gold-colored screw and 1 silver-colored screw
- The white wire connects to silver screw and this will complete the circuit to the plug
- The wire going to your Load (light, fan motor) connects to gold-colored screw, and this will let the switch control power to the Load

You can buy a simple continuity tester and check your wiring devices before purchase:
Continuity tester is used when power is turned off.
It has a battery
When you youch alligator clip to the tester point on end of tester, a light comes on.
When light comes on, that tells you the circuit is complete
For testing switches and plugs, you touch the pointer on one screw terminal, you touch the clip to another screw terminal ... then flip the switch on the electrical device to see which screw terminals cause the tester light to come on
If light comes on, then the circuit has 'continuity'
Continuity tester can be used on all sorts of small electrical devices, including troubleshooting electric water heater >>> and that's a fun project for next week.

3 way switch diagrams

Three way switch diagram: Three-way switch has 3 screws


Before replacing old 3-way switch, mark the wire connected to dark-colored screw
Connect that wire to dark-colored screw on new switch.

If you are confused which wire goes to dark-colored screw
Mark the 2 black wires and the red wire.
You are not going to do anything with the white wire.
Connect blacks and red to any screw, turn on power, and try BOTH switches
Keep trying until correct combination is discovered
Both switches must work in all possible up-down positions before wiring is correct
Incorrect wiring will not blow circuit breaker, the circuit just doesn't work until wires are right.

Four way switch is added to 3-way circuit

How do I wire the timer in a 3-way switch?

Woods 59013 59017 59018 59720 59028 etc wall timers are not made for 3-way application. They replace a simple on-off switch.

Atube T1032-3W programmable timer shows it can replace 3-way switch.
See manual

Intermatic ST01C & EJ500 programmable times can replace 3-way switch. Look at diagrams carefully. Circuit is limited to 100' distance because of battery.
See wiring diagram

Lutron makes several 3-way countdown timers that turn on light for certain length of time and then turn off light

Tip for 3-way switch replacement: Mark wire that connects to dark-colored screw. This is called the 'common' wire.
Depending on location of switch, the 'common' wire either goes to Load (lights) or it comes from breaker box as Hot wire.
