I think mine's getting that way, too. ;-p I've wondered if there's enough inductance in the brake light circuit that a freewheeling diode would help the contacts live; I doubt it. A relay (with a diode across the coil) to take the lamp current, might make the switches last forever. > So.....I have been meaning to switch over to an electric/mechanical > switch acting on the pedal (like modern cars) for some time.

I hadn't thought of triggering off that step in the pedal frame like you did. I think I'd prefer a location that didn't come so close to the angled foot plate, however. If you had moved it to one side or the other could you have taken advantage of one of the pressings in that foot plate? > Seems to work very nicely.

Doesn't the angled foot plate cover it? -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
