ABSTRACT:
Structure and method for forming a switchable shunt for a suspension assembly having conductive, insulating and metal base layers. The shunt includes a bridge in the conductive layer with either a continuous connection or small gap between ends of the bridge. The continuous connection of the bridge is severed either by temporarily moving the lands out of their original plane by stretching and rupturing the bridge or by shearing the continuous connection of the bridge. For the sheared or gapped bridge, at least one end of the bridge is moved out of plane, compressed and elongated. When released, the separated ends of the bridge overlap and contact each other to form a normally-closed switch. To subsequently open the switchable shunt, at least one of the lands is moved out of plane to physically and electrically open the connection between the separated and overlapped ends of the bridge.
