fuel cut vacuum switch

[blackbart]

Couple questions about my fuel cut vacuum switch on my 82 FJ40. Has the single wire and a vacuum line on it. Might have fried it by directly attaching test leads to battery, damn the luck.
Q-How does this switch actually work?
Q- Can I test this before reinstalling?
Q- Do I even need this if I'm de-smogging?

You won't fry it by connecting it to a battery; per the factory service manual, that is how you test it, and it works on 12 volts anyway. If it audibly clicks when you apply 12 volts, and you can see the plunger move (with the solenoid out of the carb) then it is good.

Thanks for your reply, much appreciated. Got switches mixed up. Please re-read.
