Patent ID: 8665041

Claim:
An apparatus comprising: a first substrate having a first surface and a second surface, the first substrate comprising a first coil for generating a magnetic field, wherein the first coil is substantially planar and lies in a first plane, and wherein the first coil and the first substrate are monolithically integrated; and a second substrate comprising an electrical switch that comprises a first electrical contact and a second electrical contact, wherein the first electrical contact is moved by the magnetic field, and wherein the electrical switch and the second substrate are monolithically integrated, and further wherein the first electrical contact moves selectively in a second plane that is substantially parallel to the first plane; wherein the first substrate further comprises a third electrical contact and a fourth electrical contact, and wherein the first coil is proximal to the first surface and distal to the second surface, and further wherein the third electrical contact and fourth electrical contact are proximal to the second surface and distal to the first surface; and wherein the first coil generates the magnetic field based on a first current that flows between the third electrical contact and the fourth electrical contact.
