Abstract
Abstract An improved push button switch includes a single body plate with assembled push rods or actuators fastened to the single body plate and cooperable with moving disc members, a ratchet and spring, or biasing means. The disc members are held in position by a bracket, the bracket also being fastened to the single body plate. Contact blocks are fastened to the outside of the bracket and cooperate with assembled contact cam block members of the push rods or actuators. Biasing leaf springs of the contact blocks cooperate with the actuators to facilitate switching action. A push button fastens to the end of the actuators to secure alignment of the actuators through a front plate of the switch and provide a manual interface to the operator.
