Since I'm in the process of overhauling a '39 setup on a '35, it got me thinking about this potentially weak link in the system. I know there's been countless discussions about single vs. dual systems, and the safety factor in redundancy. But this switch seems to me to be a big problem. They all seem to be made the same way, metal housing with a plastic insert that's then crimped over.

I've decided to try a '67 mustang MC setup which would be better if I used a pressure switch and had a failure I'd still have half a system, but I was wondering if anyone has used or knows of a conventional mechanical pedal switch setup that available? I don't know when Ford switched to that type switch but maybe that would be a better option. Thanks for any input.
Hey. If you are worried about a blow out on a brake switch, go back to original mechanical brakes on your 35. Give us a break man. I've been in this hobby for over 50 years and have NEVER had a brake light switch "blow out" as you seem to be worried about. Fail to work electrically, yes. Leak a little, yes. BLOWOUT, never, and have never even heard of one blowing out.
