Chuck,

The same thing happened to me and I corrected it the same way. The advantage of the mechanical switch is that it comes on sooner. If it's adjusted right, the second you touch the pedal, it's on.

The drawbacks are:
1. Sometimes the pedal gets stuck on the carpet and doesn't return to it's fully upright position, leaving the lights on. This happens to me when I park the car. I am going to put an extra spring on the brake arm to ensure it's full return.
2. The mechanical switches sometimes move around due to vibration and quit working.
3. These switches don't handle a lot of current (maybe yours does). Two 21 watt filiments put quite a strain on the switch. You usually need a relay to take the load off. That's probably why your hydraulic switch failed.

My thought is that the best solution is to have both switches and have them activate the same relay. This will guarantee operation of the lights.
