A snap action switch system actuating a movable switch contact into alternative contact with two fixed electrical switch contacts by two longitudinally rigid toggle levers pivotal relative to each other about a pivot actuated to two positions opposite a given plane through which the levers pass. The system has a longitudinally flexible arm so that as the rigid toggle levers pass the given plane the flexible arm is flexed longitudinally and the movable contact transported by the system effects a wiping and release action relative to one of the fixed contacts with which it is in contact before effecting a snap action switching action under control of a spring lever biased for actuating the toggle levers to one of the two positions on opposite sides of the given plane. An operator is provided for overcoming the spring lever and moving the toggle levers across said plane to another position on a side opposite to the plane thereby actuating the movable contact into contact with the other of the fixed contacts than that to it contacts under control of the spring lever.
