I am in need of a new stoplight switch for my 56 sierra wagon, it takes the 1/4 inch npt threads, seems the 1/8 threads are very common and as far as the on line auctions no one lists the pipe thread size. I'm not sure where to find one but I can't drive it without brake lights. Help!!
Thank you!

 

Wonder if i got a common 1/8 switch and use a 1/4 to 1/8 bushing, any reason that wouldn't work?

 

Switch may not have enough reach that way.

Is there a part number on the existing switch??

 

It just says Fasco industries Rochester NY on the electrical side and what may be 150 or 159 on the thread side. I don't think they were manufacturer specific, this is a pain because it is a 1/4 pipe thread size and it seems most were 1/8.
Thanks

 

Can you post a pic?

 

 

That's still in pretty good shape What I really wanted though, was a pic of the switch.

 

 

These guys apparently have the M/C and pressure switch combos, might wanna call 'em, and see if you can get just the switch. (it looks right in the pic.)

 

I don't have all my books with me but you can try Kanter or Andy Bernbaum. I don't know if he's still in business so you'll need to do a web search. I'm pretty sure Kanter is still around.
