Abstract
Electric switch mechanism for relays and contactors comprises a slider movable within a fixed housing and provided with cams which convert the movement of the slider into contact movement of contact pairs of the switch. The action of the slider with the cams to induce movement to the contacts is opposite to that of springs which apply closing forces to contact pairs.
