If it is a 1 way switch circuit (2core +earth cable) it should be LIVE/HOT in COM and Aux live (to the light) in L1 . I

f you have a 2 way circuit (3 core + earth cable) the aux strappers go in L1 & L2. and LIVE/HOT to COM

Remember to disconnect the power before working on electric wiring.

Pull cord switch in bathroom has red, blue, yellow wires, I've wired yellow to earth, red to com and blue to L2 - not working, why?


Is this switched used for a fan and a light or for a two speed fan??? Most switches do not have neutral or what you term ground going through them. I can only guess that the blue wire connects to the power in, and the red and yellow wires go to two different cuircuts, such as a fan and a light or to a two speed fan.

I need to hookup up a Grasslin GM40 timer controlling one load and a 120vac application. Just wondering if someone could verify the hookup terminals as I cannot read the schematic as it is mostly gone. ...


Open following links to identify timer and download manual:
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#GM

GM40 can be used for 120V or 240V 277V applications for single-phase and some 3-phase applications.
For 120Volt, set all 4 dip switches to ON position BEFORE applying power.
ON position is pushed to left.

120Volt cable from breaker box has black hot and white neutral wire.
Black hot typically connects to terminal L1
White neutral connects to terminal L2/N
This action will power the time clock and relays.

Other terminals on GM40 are the relay terminals, and these terminals are dry.
Dry means they receive no power when wires are connected to L1 and L2/N.

There are two independent relays and each relay has 3 terminals: NC NO and COM.
If you are controlling one 120volt Load, then use one relay.
Run a jumper wire from terminal L1 to COM terminal.
So COM terminal is connected to Hot.

Cable going to 120V Load has black and white wire.
Connect black Load wire to terminal NO (normally open).
Connect white Load wire to L2/N.

I have a double switch with connections for 2 lights, one in one half of the room and the other in the other half On the back of the switches are com at the top of each and L1 and L2 at the bottom of...


If there are definitely 2 reds, 2 blacks and 2 earths it sounds like the cables are switch wires from each light. Switch wires are normally twin wires and contain only the red and the black. The person installing sounds like they have used a twin and earth. Anyway the red should go the common and the black to L1. The switch should work correctly. Do this for both switches. If the switch is on when the light is off put the black into L2.

Bathroom pull cord switch i have L1,L2 and COM but i have 5 wires 2 red 3 grey what goes where?


You don't tell us where the wires come from. For instance if the red wires were from the power source, then those two red wires and the com would join. Then two greys would tie to L1 and the third would go to L2. This would give two intensities and off.

Posting a photo or having an electrician look at it might be a better idea.

If the reds and greys all come from the fixture itself it is anybody;s guess as to the connections.

Bathroom Pull switch


There are two possibilities here,

1. it is a mechanical failure i.e a part of the linkage has broken leaving the switch in the on position, did you see anything obviously wrong with the old switch?

2. It is an electrical failure either overload or arcing when the switch is being operated sometimes welding the contacts together. This can happen if the light is a fluorescent tube or ring type, which in combination with the fan start up, can cause this situation. If this is the case you need a higher current rated switch.
