Thread: I need a new brake light switch!!!

Tweet

Just replaced the same switch on my 51 Frazer. The hardest part of changing it was getting to it. Between drivers side the framerail and the body.

Here' mine monted in my 51 F1

dmw56,
Thanks, the picture is helpful. I was baffled by the fact that in the resting position the switch is "on", conducts. When your brake pedal is depressed that allows the switch to be "on" no matter how far the pedal goes forward. At least I understand how yours works but I have a MC under the floor so I have to think about this a bit.

IF you buy a switch from a late model GM car with cruise control, there are two circuits, one opens on brake application and one closes. The one that opens can be used to unlock your converter and the one that closes is the brake light sw. From GM, the switch is less than $10 and is all mechanical....no hydraulics.

I have heard that the switch (pun intended) from the hydraulic-actuated style to the mechanical style is because you can actuate your brake lights earlier....as soon as the pedal is touched, the lights go on...theoretically sooner than waiting for the pressure. Of course, this allows the nimrods who left-foot brake to keep their brake lights on for miles and miles. (It's OK to left foot brake at the starting line).
