Simulation and Test of Bistable Inductive Micro-Switch

Abstract:

Article Preview

Inductive micro-switch is an integrative device of a sensor and actuator. It can not only induce an external acceleration, but can also be controlled by the external acceleration to realize the trigger action. However, its malfunctions related to “fail-to-closure” and “transient-closure” result in low reliability and weak anti-jamming capability. A new bistable inductive micro-switch is presented based on micro size adhesive effect. The dynamic simulation is obtained by Comsol software. The simulation shows the threshold acceleration is 23.6g, and the response time is 0.38ms. The micro-switch is tested by a centrifuge. The test result shows that the threshold acceleration is 24g.The relative error between the theoretical analysis and the test result is only 1.6%.
