[T3] DOT 5 and brake light switches

[Sean Bartnik]

Jim,
Very interesting stuff. Thanks for taking the time to autopsy the switch in the interest of bettering the knowledge base. 

To answer your question, those switches cost around $20. 

One other possibility for the apparent failure I guess would be the possibility that sometime after installation, an air bubble worked itself into the switch and was preventing the proper transfer of hydraulic pressure to the diaphragm in the switch. That's the only other thing I could think of that might cause the same symptoms if indeed the switch itself was good. 

Glad to hear the internal construction is like that of the original Ate switches. 

I replaced the switch that you cut open with another identical switch that I bought from the same supplier at the same time. It is also FTE and the only difference is that it has the number 185 stamped on it instead of 165 which was stamped on the one I sent you. 

The new FTE switch is still working properly. Obviously I'll update if/when it fails.
