    • 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.
    • 柱塞开关和方法包括具有轴向对准的第一和第二柱塞的多作用柱塞装置,使得第一柱塞位于第二柱塞的中心。 第二柱塞具有用于支撑至少一个导电擦拭器触头的环形壁。 柱塞开关还包括具有不同负载常数的第一和第二偏置构件,使得第一和第二柱塞在使用期间以不同的负载致动,并且多个端子用于传送电路径。 开关还包括具有用于支撑柱塞装置的中心开口的壳体。 第二柱塞和第二第二偏压构件与导电擦拭器触头配合,使得第二偏压构件从正常位置压缩到第一致动位置导致开关组件的状态改变。
