Abstract
An ON/OFF push button switch is disclosed which includes a housing, a fixed contact fixedly mounted on the housing, and a movable contact adapted to be brought into and out of contact with the fixed contact. An operating portion of the disclosed switch is supported in the housing in which the movable contact is to be movable in a direction towards the fixed contact. A contact connect spring located between the housing and the movable contact is provided to urge the movable contact towards the fixed contact. A contact release spring is located between the housing and the operating portion to urge the operating portion away from the fixed contact with an urging force greater than that of the contact connect spring. A coupling arrangement is provided for releasably coupling the movable contact and the operating portion together with the movable contact being inhibited from being moved away from the operating portion towards the fixed contact. Operation control provision is made 1) for maintaining an ON state where the operating portion approaches the housing to put the movable contact in contact with the fixed contact and for 2) releasing the ON state when the operating portion is further pushed down towards the housing in the ON state.
