I think if you connect on each switch:
pin 1 (COM) to the motor
pin 3 (NO) to batt+
pin2 (NC) to batt-

I don't think you will have blown them up as long as you keep the motor connected across the 2 common pins, you should be ok.

Let me know if this works, or if you want me to draw a circuit diagram.

Thanks to the help of Paul I got the linear control working. At least this mock up, which powered a small 12V motor. The idea is to make a sandwich with some polycarbonate as the bread and the microswitches as the filling. Conveniently the mini servo I am using is just the right height to align with the arms.

I need some long 4mm bolts and some longer 1.5mm bolts, and in the final version the polycarbonate will shield the arms too. (Pictures updated with bolts fitted)
