ABSTRACT:
A plunger actuated, electrical switch uses a lost motion mechanism to prevent the switch from making and breaking contact more than once for each plunger depression. The plunger drives a contact element from a rest position to a contact position where electrical communication between two terminals is established and remains established until the plunger has retreated a fixed amount through a range of lost motion, whereupon it re-engages the contact element and drives it toward the rest position, breaking electrical communication between the terminals.
