ABSTRACT:
An electrical switch suitable for use singly or in tandem with other switches and/or with a variable resistance control. Each of the tandem switch housing sections defines a cavity and provides an annular bearing member rotatably supporting the periphery of a disk shaped switch actuator. The switch actuators close the cavities of the respective switch housing sections and each of the switch actuators carries a cam disposed near its periphery in an interference path with a contact spring biased between spaced projections on common contact means. The contact spring is provided with a pair of end members pivotally secured to the common contact means and a U-shaped section joined to the end members. The cam engages the bight portion of the U-shaped section for moving the legs of the U-shaped section into and out of engagement with first and second contact means disposed in each housing section. A plurality of lugs and lug receiving notches on each switch actuator provide the means to interconnect respective switch actuators for simultaneous rotation thereof.
