ABSTRACT:
A micromechanical switch and a method for operating the micromechanical switch between an open position and a closed position by moving a magnet between two positions. The magnet produces a magnetic flux that travels through one of two different conductive layers. The magnetic flux within the conductive layer forcibly draws a contact element into contact with the conductive layer and electrically shorts the conductive layer. Depending upon which conductive layer is shorted, the micromechanical switch is set in either the open position or the closed position.
