PRINTED MEMBRANE SWITCH ACTIVATED WITH MAGNETIC FORCE AND APPLICATIONS THEREOF

摘要

A magnetically actuated membrane switch shiftable between a rest or unmagnetized state, and an activated or magnetized state in the presence of a magnetic field. The membrane switch generally includes first and second conductive traces shiftable between a closed position wherein the conductive traces are electrically connected to make a circuit, and an open position wherein the conductive traces are electrically isolate to break a circuit. The membrane switch further includes a magnetic material that is activated by a magnetic field, thereby effecting a switching operation from a rest position to an activated position, and vice versa.

1. A magnetically-activated membrane switch comprising:
a first substrate including:
a first conductive trace,a second conductive trace, anda gap separating the first conductive trace and the second conductive trace; a second substrate including:
a conductive shunt comprising a magnetic material, the conductive shunt positioned opposite the gap; and a space layer separating the first substrate and the second substrate, wherein upon application of a magnetic field, the conductive shunt is shiftable between a closed circuit position wherein the conductive shunt bridges the gap and contacts at least a portion of the first conductive trace and at least a portion of the second conductive trace, and an open circuit position wherein the shunt is spaced apart from at least one of the first conductive trace or the second conductive trace.
