Filed:

Oct 25, 2011

Appl. No.:

13/281310

Inventors:

Kevin Wilson - Lake Forest CA, US
Robert Tarzwell - Freeport, BS
Patrick McGuire - Oakland CA, US

International Classification:

H01H 45/00

US Classification:

335203

Abstract:

A switching device structure having a top layer and a bottom layer, each layer comprising a body of magnetizable material, such as permalloy, disposed within a coil wherein an armature is suspended in a cavity between the top and bottom layers, the armature having ferromagnetic material disposed on a top and bottom surface thereof. Each body of magnetizable material may be pulsed by its respective coil to switch it from a magnetic state to a non-magnetic state and then subsequently pulsed by the coil to switch it from the non-magnetic state to a magnetic state.

Abstract:

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.
