Abstract: A low force switch assembly having a single pole, double throw switch action wherein a one-piece contactor having a frame with longitudinal side members, a contact portion, a blade portion, and a pair of auxiliary lever arms are positioned within the switch housing by locating the contact portion between first and second contact members mounted to the switch housing and by anchoring the blade portion and auxiliary lever arms to points on a common terminal positioned within the switch housing and extending outwardly therefrom. The common terminal includes a pair of fulcrum extensions extending inwardly within the housing intermediate the ends of the common terminal for engaging and anchoring the auxiliary lever arms. A switch operating plunger extends outwardly from the switch housing and is engageable with the one-piece contactor. During depression of the operating plunger, the contactor is moved downwardly and the blade portion drives the contact portion to engage a selected one of the first and second contact members to complete the switch action. Upon release of the depressed plunger, the compressed lever arms bias and return the actuated plunger and the contact portion to their unactuated condition.
