Brake Light Switch WARNING

Warning, after posting info on a thread about replacement brake light switches for the M35A2, I called The NAPA tech line to get the specifications for the Ech SL 134, brake light switch. It fits and has been used by others, to replace the original BFS operated switch.



The NAPA switch is rated for 1200psi maximum for 5 seconds. It is NOT dot5 compatible.


Bjorn had posted pressure readings on his brake system and it sounds like this switch is not rated high enough for a deuce or 5ton, even if you have switched to dot3.

Good info Eric! Thanks!

This is just one more thing that "seems" to fit but does NOT do the same thing.

Thanks for the heads-up doghead!

See, it pays to look at the specifications....
