Mag mount kill switch for e-bikes
Description
A set of two parts, for mounting a magnetic motor kill switch onto a Shimano BRM446 hydraulic front (RHS!) brake for e-bikes. Clips onto the rubber shroud of the handlebar/cylinder bracket, and the other clips onto the lever itself. NO bolts, tapping or anything, so fit, try, discard if not suitable with no mods to your lever/bracket. I printed with 50% fill, PLA. Used a cheap <50p Chinese N.O. push to make switch. The setup flexes a bit, to allow for solid contact of the switch. It will fail open circuit, so the motor will still work if it all turns to mush. :) This took many iterations to get just right, and I've found that it still needed to be tie-wrapped to the handlebar bracket to keep it in place. Total cost for me was about 70p. And much messing!
