Abstract
A forced disconnect sequence switch is provided with a plunger that has two surfaces at its bottom portion. The two surfaces are disposed in planes which are displaced from each other so that cams can be actuated at different positions of travel of the plunger. The cams are sequentially rotatable to provide a positive break characteristic to the sequence switch. If either of the movable contact structures becomes welded to an associated stationary contact structure, each of the movable contacts are mechanically urged into separation sequentially by the cooperative action of the first and second surfaces of the plunger and their associated cams.
