[Milsurplus] [ARC5] T-17 Switch

Mark,

 

All T-17’s are functionally interchangeable.  But there are several different models, that I know of 

 

T-17 (no suffix letter)

T-17-B

T-17-C (maybe)

T-17-D

T-17-E 

T-17-F 

 

Plus most were built on multiple Signal Corps Orders between at least 1929 and 1954, with most being between 1941 (late 1940 Calendar Year) and June 1945.

 

Those with the same model letter and Order Number can be counted on to have interchangeable parts.  Those with the same model letter but different Order Numbers usually have interchangeable parts.  Those with different model letters generally do not.

 

Some were also built by the French on NATO contracts.  Parts from them are mostly not interchangeable with any of the US built ones.

 

At any rate, if you want a part, you need to give the rest of the ID info.  And as there are no relays in a T-17, it isn’t clear at least to me what part you broke.

I had never taken a T-17 microphone apart and thought the switch/relay assembly was a friction fit assembly.    As I gently tried to pry the relay section up, the Bakelite portion broke.

 

So after it's busted I see how the switch is screwed in....

 

By chance,  anybody have a spare button/relay (for 3 conductor cables) they'd care to sell?   A bust up mic with a good switch/relay would work too.

 

Since the switch pushes against the relay arms,  I'm not sure just using JB Weld or similar would fix the break.   Anybody every do this successfully?

 

Crud.......
