Rotary SUT Load Switch

AvFan said:
I'm resurrecting this mothballed thread in hopes @HalfApt or others can clear up my confusion since I'm about to incorporate the switch PCB in a V3.2 build.

Do the both the GREEN and RED connections shown below need to be made, even if only one switch is used, to apply the paired resistors or capacitors (e.g. R1/R13, C12/C24) of each switch to both channels?

Sorry, I'm not getting thread notifications, and I'm not online very often either.

Yes, both need to be connected. Each switch controls a specific load type (R or C) for BOTH channels. Arranged like this:

Thanks for confirming what I suspected was the case. @mkane also confirmed how to wire up the switch PCB using his switches and board.

FYI, the price of the Greyhill switches has gone up about $5 with the version with a 1/4" shaft at Mouser listed at $40.63 each (71BDF30-02PAJS) but they have 45 in stock.
