ABSTRACT:
At least one stationary electrical contact is fixedly mounted in a housing and an equal number of corresponding movable contacts is affixed to a movable member pivotally mounted within the housing and positioned thereon to mate with the stationary contact, however, first biasing means are coupled between the movable member and the housing to retard mating of the contacts. An actuating member is slidably pivotally mounted within the housing and adapted to engage the movable member, with biasing means coupled between the actuating member and the housing to overcome the first biasing means and urge the movable and stationary contacts into mating relation when the actuating and movable members have been engaged. Release means, controlled by circuit fault sensing means, are positioned adjacent the actuating member for causing the actuating arm to be released from the movable member when predetermined circuit conditions are detected by the sensing means, to disjoin the stationary and movable contacts.
