Simple solution for brake lights

I use this switch with every brake system I plumb. No mechanical switches to adjust or position just right, just plumb in line and run the wires.

Excelent part!

November 07, 2010
I built my Model T roadsters brakes from scratch. I designed under floor mounted pedals. You should use a line pressure switch on these types of system because dirt and water could enter and destroy an ordinary push button type switch mounted under the car.
Pros:
  • A VERY GOOD VALUE
Yes, I recommend this product.

Wiring Instructions Don't mean to sound stupid, but I mounted this on my proportioning valve. However, no instructions as to what to hook up to the two terminals coming off the brake switch.

Hook a hot wire from your fuse panel to one terminal and the wire going to the brake lights to the other terminal. Use a 20 amp fuse in the panel.

doesn't matter this is simply a " make or break" switch . Pressure "makes" the elec. circuit sending 12V to the brake light circuit.
October 29, 2012
Jason
Power goes into one terminal and out the other when the pressure switch is closed under pressure. Without pressure the switch is open and no current will pass thru the switch and out the other terminal. It could mount to one port on a proportioning valve if so desired as long as it will receive pressure from the master cylinder once the pedal is depressed and pressure goes out to the brakes. The output power feeds the brake lights or goes into the turn signal switch depending on your application.

is this type of switch used for brake lights? is in tail lights, turn signals and brake lamps? does it take the place of a push butting type that would be mounted on or near a brake pedal?

Yes this is used for brake lights using the brake line pressure to close the switch. Use this if its easier to set up than a mechanical switch on the brake pedal linkage.
January 10, 2012
John
91031305 This pressure brake switch can be used in place of an existing push button or mechanical switch for the brake lights. Depending on the application, if one bulb or filament is dual purpose for brake and turn the leads will have to work in conjunction with the turn signal switch and be wired accordingly.

If you can't find a pigtail just use a bullet splice for 14 to 16 gage wire on your two wires they are fully insulated and fit on the two pins perfectly.

Sorry, we offer the switch only but pig tail is only offered with switch
