@Former Member posted:I had a diode in place to stop reverse voltage spikes pretty sure they were undersized for the application. Its what I had on hand and they were doing alright until I had a few derailment at the switch. Bigger ones are on order
That diode wont do the job of a bidirectional TVS... a 33 volt TVS diode wired from the common outside rails to the center rail somewhere in the switch body should help extend LED life.
