Abstract
An electrical switch apparatus includes at least a pair of electrical switches and an actuating mechanism for sequentially actuating the switches. Each of the switches includes a push button which is movable between first and second positions, and the actuating mechanism includes an actuator which is movable between a first position, at least one intermediate position, and a third position. The actuator includes a cam for each of the push buttons. One of the cams is engageable with one of the push buttons to move the push button to its second position as the actuator moves to an intermediate position, and the other cam is engageable with the other push button to move the push button to its second position as the actuator moves to its third position. The actuator mechanism includes a first spring for resisting movement of the actuator from its first position to its intermediate position, and a second spring for providing a greater resisting force as the actuator moves from its intermediate position to its final position.
