ABSTRACT:
A method may be employed to assure that a switch measurement system accurately measures a torque/angular displacement profile for a rotary switch. A procedure may be employed that aligns the rotational axis of the switch with the rotational axis of the measurement unit of the switch measurement system. Also a procedure may be employed that monitors secondary forces to assure that proper alignment and calibration has been achieved.
