ABSTRACT:
An electrical switch comprises a snap-acting actuator blade movable with a snap action between two configurations to control the making and breaking of electrical contacts and a latching mechanism which, when the actuator blade has snap-acted in one sense to break or make the contacts, prevents return movement of a movable contact carrying member until the latching mechanism has been positively released. The latching mechanism comprises a pivotal rigid member having an arm defining an engaging portion, for restraining return movement of the movable contact carrying member, and a biasing spring which urges the latching member in the movable contact carrying member engaging direction.
