ABSTRACT:
In a controller of the type having a body, a pivot member within the body and an actuator shaft on the pivot member, a push button switch for the controller includes a handle fitted over an external end of the shaft and having a longitudinal opening therethrough, a push rod slidably positioned within the opening, a collar connected to the push rod, a switch operator which slidably engages the collar, and a switch positioned between the switch operator and the body such that, as the push rod is displaced toward the body, the push rod urges the collar to displace the switch operator toward the body thereby operating the switch. The switch operator preferably has an outer convex or arcuate bearing surface and an opening through which passes the actuator shaft. The sliding collar preferably has a lower concave portion which slidably engages the bearing surface of the switch operator, so that the push rod can actuate the switch at any given position of the controller.
