Brake..Motor kill switch.

Look at Ebay Item #290244117019, 10 of them for 10 bucks, digikey.com sells over 5,000 different styles of these, look for snap lever switches. Any appliance parts store will carry them. All electronics supply houses will have them as well. Should be under 3 or 4 bucks if you get it locally, Get the DPDT type if you want to run a stop light as well.

Very cool idea. Another approach would be to mount the kill switch directly under the brake lever on the handlebars? What I invision is a button, much like the built in kill switch on my throttle twist grip, but mounted under the brake lever so a firm squeeze would activate it. Casual braking would not move the lever far enough to press the kill button but a hard application would. I'm going to experiment with this and if it works I'll let you know. It would be our answer to a truck's "Jake Brake".

Found this on another thread. Sorry, can't recall who posted it but if the switch action is adjustable for sensitivity this thing could work.

When I was first thinking about this, I thought about putting the switch on the brake lever housing, The trouble I had with it was that it would kill the engine every time I touched the brakes. Personally I did not want that to happen, sometimes I want to be able to let up on the throttle and "Kiss" the brakes a little to slow down without killing the motor. The way I ended up doing the project, I was able to adjust the tripping barrel on the brake cable so that it would only kill the motor if I really clamped down hard on the brakes. I would love to see if anyone else build this, Please post you Pics !!!
