ABSTRACT:
Conductive and resistive tracks mounted on a circuit board are slidingly engaged by a bridging contact carried by the actuator arm of a controller that is operative to open or close switch contacts at the limit positions of its travel. The controller is pivotally supported in a non-conductive box within which the circuit board is releasably positioned. A manual control arm projects from the controller through a slot formed in a mounting plate covering the open end of the box.
