This should at least be close: you'd have to transfer the lever over from the old switch.

Honeywell Microswitch

If not there is a whole series of different levers to chose from.

Steve this switch will not work! I might have to find a junker machine! This switch the original has two wires soldered to it the switch you are showing me takes three wires! I have some of them!

This is a three terminal switch (We'll call them "A,B,C"). When the button is depressed A is connected to B, but not to C. When the button is released A is connected to C, but not to B.

It's a selector. Two of these are used on the motor terminals of DC motored machines to select forward or reverse. One selects (+) when the other selects(-).

What you can do to control the lamp is connect A and B and leave C flapping in the breeze. Now it's just "On" or "Off".

What happened? Did the lamp stay on all the time, did it not come on at all?

This could get a little freaky if you connected C instead of B: The lamp would only come on when you turned it off!

Use C and B without A: just darkness!

I did a donor transplant once and used a former motor switch: the lamp switches take a beating.

The lamp does not come on at all! I replaced the lamp socket and the lamp no luck! So I checked the lamp switch and found out its bad! So once I replaced it that should solve the problem!

Nice repair!

All those insulators, switches and plates stacked up!

(Nothing to do in a hurry!)

Best of Luck!
