Purchased June 1, 2021 Didn't last 4 months Edited 10/30/2021 I have 3 amps with a total of 4700 watts/80 amp fuses on board (30 on one amp, 25 on the other 2)). That circuit breaker sucks. I've been searching for days trying to figure out why my amps won't turn on. Finally today I decided to check the integrity of all circuits and switches. This switch failed and never worked. I hope I didn't blow up my amps so I bought this switch first.
