Currently in the process of designing the main power switch for #Torquee.
It needs to switch the 48V battery voltage at up to 500A.
I'll be using a EV200/GV200 contactor for this.
But I need a 12V supply and pre-charge circuit so I don't explode the contacts when trying to instantly charge ~8mF of input capacitance of the 2 #startergenerators to 50V in microseconds :D
So I'm designing this PCB, that'll screw on top of the cable lugs and connects to GND and actual switch input.
