The electric switch has an angular movable contact element formed by a pair of angled legs interconnected at a bend, with the outer surface of the bend bearing on a support. A movable contact at the end of one leg of the contact element is engageable with a fixed contact. A spring-loaded swivel member bears against that side of the leg, carrying the movable contact, opposite to the side facing the fixed contact, at a point spaced from the bend, and is operable by a slidable switch actuator movable in a contact element displacement direction. A loading spring has one end engaged in the swivel member and its opposite end engaged in the actuator. The swivel member carries a movable contact or is formed with a contact surface which, responsive to movement of the actuator in a switch closing direction, is engageable with an additional fixed contact of the switch. A camming device is cooperable with the swivel member to effect a direct engagement, as distinguished from a sliding engagement, of the swivel member contact or contact surface with the associated fixed contact.

Electric switch

An electric switch comprises a closed switch housing which is adapted to contain the switch contacts which has a guide bore for guiding a shaft portion of a switch operating member or push button. An operating member lock included an exterior housing portion associated with the switch housing which has a lock guide channel and a lock member bore intercepting the guide channel. The lock member is movable in the bore to engage a lock actuator which is connected to the switch operating member and is displaceable in the lock guide channel. The lock member is engageable with the lock actuator when the switch operating member is in an actuated position in order to lock the lock member and the switch operating member against movement.
