We have had two longacre switches fail, they were both purchased during the same time period.

From the looks of both of the switches the failure was on the smaller of the 2 posts. In both cases.

But one car had little to NO electrical strain on the Alt, (no lights not a whole lot of anything running). The second car was a enduro car with tons of stuff running, normal lights with HIDS, plus 4 other PIAAs, Electric power steerings, and all of the factory gauges in the car.

I just stay away from using the smaller posts except for very low loads.
