I will guarantee you that is exactly what that valve does.
But don't believe me, open a bleeder and stomp the brake.
Why won't anybody do this?
If I designed a valve that could operate a switch, AND cut off a leak, why not both?
I would guess at this point, if some of you SAW proof of "no dual brakes" you couldn't believe it.
If you read the responses, 383MAN has already stated this happened to him and he had brakes in the other half of the system. AND he didn't have a safety switch installed. So that pretty much proves that your dual master cylinder provides braking to the good half of the system in event of a failure of the other half. Once again the SAFETY SWITCH is just that... a simple hydraulically activated electric switch. It shouldn't be such a difficult concept to understand. Perhaps this video will help those who insist this switch is more than it really is understand this concept. You'll have to understand... this video was made for training those dumb Mopar service technicians on dual brake system.

The following video also explains what the brake safety switch does... but is geared more towards people who can read and write.
