Hello,i have one of these SPDT switches connected to transformer to power it on/off now I would like to make the light work on it but cant figure out how to wire it properly.I want to have it light on when I use the switch so I know that its working.

My ideas:

Version 2 probably wont work since it not really connected to anything.

 

Do have a wiring diagram of the switch?

 

What is the part number of the switch? Usually, the light is connected to the actuator and a stationary contact, meaning the light will turn on when the switch is in the on position, assuming you are putting a large enough voltage across it.

Also, it is advisable to wire your switch across live, not neutral. For one, your transformer winding my be dropping the voltage enough to prevent the light from turning on. And two, if you turn off your switch, most of your circuit still has live connected to it, meaning you can be shocked touching anything copper.

Cant find anything else.

PS

Found this one some Russian forum?

 

You should be switching the hot line, not the neutral. The light will then be tied to neutral. If you check, you should find the light connected between the center tab and one end. Test with an ohm-meter.

 

The wiring diagram you pulled from the forum makes no sense. The light will have either neutral or live across both contacts, it will never turn on.

My suggestion would be to wire the utility live to the contact immediately beneath the O (the off arm of the switch actuator) and the transformer winding to the contact immediately beneath your switch actuator or the rocker.

 

Diagram looks good. (POST 4)
Bottom line is neutral. (same for 120vac)

edit:
If it's a SPST switch with pilot.

 

No1 you should not be switching the neutral, the line is switched to control the equipment and the neutral is connected to the lamp terminal on the switch.
Do not connect any ground wire.
Max.
