ABSTRACT:
A shaft position indicator in which the mechanical position of switch actuation is variable with the control of the switch actuators. The switch actuators are controllable through a series of setable cam operated screws or non-mechanical contacts that intercept the switch actuators as they are moved from one position to another, the movement of the cam operated screws overlapping the travel of the switches during one revolution of a lead screw moving the cam operated screws. The input shaft rotation is field adjustable to accept input rotations from 1 to 25 or more revolutions, resulting in accuation of the switch in output performance.
