'39 H Starting Switch

I think mine is original, but it seldom works. Is it possible to remove it, take it apart, clean it, re-assemble it and get it to work again?
 
I have taken a few apart. There is a copper piece inside that makes a connection between the two terminals. The power is then passed from the live terminal to the other terminal. After many years of use, the copper will erode and it may not work very well. After I opened the switch, I removed the copper strap and turned it over and I re assembled it and according to my little ohm meter, it is working. Whether or not you can get the copper strap re attached to stem, will determine if you can get it to work again. There are two insulator washer/spacers that need to be installed correctly. Pay close attention to them.
Good luck
 
You may ridicule me, but what I do when some electrical gizmo acts up is reach for the PB Blaster. I spray it inside, outside, all around and all over. I just really goose it in there. The stuff lubricates, removes moisture, removes corrosion, prevents corrosion, makes things smooth again. I've had it fix many many electrical things. It works and keeps on working. Just my humble experience and opinion.
 
My calculator shows 2018 minus 1939 means it's 79 years old, may be 80 depending how long it sat on a shelf before being installed.

It is possible to take it apart and put it back together again. It probably is not so much that it is dirty as it is that the contacts are burned and worn. Depending on just how badly those contacts are worn, you might be able to file them smooth again. You have nothing to lose except time. If you decide to go for a new switch, pay attention to who you get it from. Some of the new switches have issues also.
 
YES its possible I've done it but it depends on how bad its burned pitted and corroded if a fix will work or not... Its worth a try...

I will add that the copper strap may not be straight any more and if you bend it a little bit, it may fix your problem, by making better contact to the terminals.
