I installed a hydraulic brake switch on my rear brake about 2 years ago. I only have 250 miles on the bike since then (I know, I should ride more!!), and the brake switch started working intermittently, then finaly quit. I disconnected the wires, and using an ohm meter, I noticed that the switch was still working when I pressed the pedal. So then I connected 12V right to the brake light, and the light worked just fine. I measured the current draw and it was around 1.7A (just right for a 20W bulb). Even when I connected 12V to one side of the switch, then pressed the pedal, I measure 12V on the other side of the switch (without connecting it to any load). Once I connect the brake light, the switch does not close anymore. Anyone ever have this problem? I don't know to much about these pressure switches, but is this a typical failure characteristic of it? I hate to keep having to replace these things only after a couple hundred miles of use. Maybe I bought a cheap one. Thanks.
