Failsafe pin switch
I have a power expander pro which I was using with Fromeco Regs and Fromeco FS switches. I'm getting rid of the regs but wanted to use the FS pin switch to go directly into the power expander where it has the switch connection. The Fromeco switch is two wires and the Smart Fly is three. Anybody know the how the smart fly switch is actually wired internally? Thanks.
