PUSH-ON-PUSH-OFF BISTABLE SWITCH

摘要

A push-on-push-off bistable switch is disclosed. The push-on-push-off bistable switch includes an actuator, a lever mechanism connected to the actuator and having a long portion and a short portion, a bistable switch mechanism connected to the short portion, and a displacement amplifier mechanism connected to the long portion, wherein the bistable switch mechanism and the displacement amplifier mechanism are substantially parallel to each other, and the displacement amplifier mechanism has a driving portion and is adjacent to a driven portion of the bistable switch mechanism. The switch of the invention requires only one single actuator and thus can reduce the size of components, increase good throughput, simplify operational complexity and achieve the push-on-push-off switch effect. In addition, the displacement amplifier mechanism and the lever mechanism can magnify efficacy of the actuator to increase the energy saving effect.
