Multi integrated switching device structures

摘要

A permanent magnet is pivotally mounted in a top spacer layer of a switching device and rests on a flex arm created in an underlying flex circuit layer. The underside of the flex arm rests on a thin bar formed in a lower spacer layer beneath which lies a base layer including an electromagnet. Activation of the electromagnet causes rotation of the flex arm to thereby close and open electrical contacts formed respectively on the underside of the flex arm and on the top surface of the base layer.

1. In a switching device or relay, the structure comprising:
a permanent magnet pivotally mounted in a top spacer layer; a flex circuit layer disposed beneath the permanent magnet and comprising a rotatable flex arm, a surface of the permanent magnet resting on the flex arm, an underside of the flex arm carrying first and second electrical contacts; a lower spacer layer beneath the flex circuit layer and having first and second openings therein separated by a thin bar upon which the flex arm rests; and a base component positioned beneath the lower spacer layer and comprising an electromagnet actuatable to rotate the flex arm clockwise or counterclockwise; and third and fourth electrical contacts positioned on the base component to respectively make electrical contact with the first and second electrical contacts when said flex arm is caused to move in a selected direction by actuation of said electromagnet.
