Abstract: A prime mover adapted for selective energization across a power source. The prime mover has a winding circuit, a rotatable assembly, and an electrical switch including a housing, a first pair of switch means adapted for connection in circuit relation with the winding circuit, and a second pair of switch means adapted for connection between opposite sides of the power source. A pair of camming means is movable in the housing for engaging and actuating the first and second switch means pair and has a force receiving portion exteriorly of the housing. A speed responsive system is associated with the rotatable assembly and the force receiving portion for moving the camming means to effect the operation of the first and second switch means pairs.

Abstract: An electrical switch has a housing with a plurality of switch means movable therein for operation between circuit controlling positions. Means is movable in the housing for engaging each switch means of the switch means plurality to effect the operation thereof from one of the circuit controlling positions toward another of the circuit controlling positions, respectively. The engaging and actuating means include means interiorly of the housing for camming at least two switch means of the switch means plurality so as to effect the operation of the at least two switch means from the one circuit controlling positions toward the another circuit controlling position thereof.
