I'll pile on here too Alex. The stock Kitfox config has the whole current draw of the trim motor getting pulled through it. So the contract wear that Eric talks to is greater (read happens faster). If you are using the Safety Trim, then the current through the switch is dropped to mA vice Amps. Lot less wear and it gets you to Eric's "signal-level" service. Since I didn't use my panel switch, I'll be more than happy to give it to you.
