Question about Gardner Bender #GSW-SK Door Switch

Wiring Door jamb switch

I installed a Gardner Bender GSW-SK jamb mounted switch in pantry door so light will come on when door is opened. The existing light fixture is a pull-chain type. Two black wires coming into the junction box are wire-nutted together with a pigtail coming from it to a set screw on the light fixture. Two white wires coming into the junction box are also wire-nutted together with a pigtail coming out to the other set screw on the fixture. Where do I connect the two wires coming from the jamb-mounted switch?

    To clarify, I have 2 sets of wiring coming into the j-box from one side and 1 set of wiring coming into the j-box from the other side. The 3 white wires are wire-nutted together with a pigtail going to the silver terminal. The 3 black wires are wire-nutted together with a pigtail going to the bronze terminal. Then I have my 1 set of wiring coming into the j-box from the door jamb switch. I did disconnect the white wires from each other and tried different combinations of connections that involved connecting one of the switch wires to one white wire and the other switch wire to 2 white wires with no success. Now what?

I'm going to guide you on how to create what is known as a "switch leg".
1- run a 12-2 w/ground wire to the light fixture from new switch.
2- connect black wire "hot wire" to the shiny bronze tinted terminal on switch.
3- connect the white wire " neutral " to the silver connection on switch.
4- connect the naked copper wire " ground " to the ground terminal on switch
5- Disconnect the two white wires in the junction box from each other.
6- Connect the ground to ground in j-box
7- Connect the black to one of the whites in j-box
8- connect the white to the other white in j-box
9- wire nut and tape all connections
Oh and be sure that you turn off the breaker before you start. Hope this helps. Good luck.

    ok then separate the wire that is coming from the fixture from the other white wires and it will go to one side of the switch and the cluster of white wires will go to the other side. that will complete the circuit when the door is opened.

Let's get started:

2) You have 4 cables that enter the box.
3) Only 1 cable will be Hot and Neutral from breaker box. You must identify this cable first.
Here is drawing:

I am installing a new closet with double doors. Can I put a GS-SK SPST Switch Kit in both the left and right jambs, or must I use only one kit in one jamb? Thanks.

You can use a switch in both jams, just wire them in parallel. For example, if your light outlet box contains the supply (hot) cable, you would run a cable from _each_ door switch to that same box. The hot would then be connected to the line side of both switches (pick a wire from each switch), and the load side (the remaining 2 wires) of both switches would be connected to the light. That way either switch will operate the light, and the light will shut off as long as both doors are closed.

How do I know which wire coming from the GSW-SK switch is the hot or black and which is the white or neutral?

It doesn't matter. The switch is just a normally "on" switch so it just breaks and activates the power to the light.
I generally, just for my personal way, I look for a thin stripe on the wiring, ro a small bead along the casing and us that as a reference, but in that switch, it makes on difference. I used the thin line as "negative" for myself but just for reference.

My SPST switch kit came apart during installation. Do you have a diagram that can show me how to properly put it back together?

If it came apart your best bet would be to purchase a new one. These switches take a lot of pressure on them as the door is constantly being opened and closed. If you did get it back together I do not think it would last long.

I'm trying to connect a GSW-SK door switch to an led rope light. The circuit breaker trips every time I plug the power cord into the outlet. Any ideas?

The circuit breaker trips because you have some sort of short circuit. Use a Meter set to OHMS, and try to find the "Short". Check the wiring in the Plug also.

Can you describe how to wire this switch between an electrical outlet and an overhead fluorescent light? I have recessed the electrical switch box in the door jamb. There are two black wires on the rear of...

The 'comm' on that switch is very misleading. Generally that would refer to the white (or neutral wires), however in this case it doesn't. All a switch does is interrupt power. One black wire is power into the switch, and the other black wire is power out of the switch. So, all you have to do is leave the whites connected to each other, and connect one black wire to one black lead on the switch, and connect the other black wire to the other lead on the switch. Everything should work perfectly after this.

Circuit breaker trips

leave the original whites connected together, connect the new switch in series with the two black wires (one black to the top of the switch, the other to the bottom),

p.s. the switch is grounded through the mounting strap
