Yep, so I replaced it with an identical new Otto switch, also supposed to be good for 25,000 cycles at 16A at 28V, which failed while flying back from SNF a few months later. Since it's a DPDT (double pole double throw) switch, there was a fresh unused pair of poles available at a flip of the switch, and the prop didn't even even spin down before it fired back to life again. A bi-color LED next to the switch was my instant clue...when the bright green LED went out at the same time the ignition quit. I've since replaced that DPDT switch with a much higher quality Honeywell DPDT relay rated at 15A at 250VDC.
