ABSTRACT:
This invention relates to a snap action type of switch in which a generally G-shaped sheet metal strip has a fixed terminus and a movable terminus forming an inwardly and upwardly extending arm which is pivotally mounted in a knife bearing. The midportion of the strip extends between fixed contacts and has a contact thereon which alternately engages the fixed contacts. An actuator is movable transversely of the strip and engages the arm of the strip to move the movable contact in the opposite direction relative to the movement of the actuator.
