    I get the circuit I was referring this to the OP. I don't understand the reason of using two switches to turn the motor on and off when one will work fine. Like on the Hornadys LNL Case Feeder. One switch in the normally closed position in the top of the tube, tube fills, forces switch arm open, motor shuts off, easy. Half as many parts and wiring. My question is why 2 switches? What is the advantage?
    45 ACP because shooting more than once is just silly!!

    With one switch at the top of the tube, the motor would cycle every time the brass in the tube dropped below the switch; every time a case is fed. I would cycle every time the handle is pulled. With one switch at the bottom of the tube, how would the motor shut off when the tube is filled?
