Abstract
A plunger switch and method comprises a multi-action plunger arrangement having first and second plungers in axial alignment such that the first plunger is centrally located about the second plunger. The second plunger has an annular wall for supporting at least one conductive wiper contact. The plunger switch further comprises first and second biasing members having differing load constants, such that the first and second plungers are actuated at different loads during use and a plurality of terminals for communicating an electrical path. The switch also comprises a housing having a central opening for supporting the plunger arrangement. The second plunger and second second biasing member cooperate with the conductive wiper contact such that compressing of the second biasing member from a normal position to a first actuated position results in a change of state of the switch assembly.
