Abstract:
1. A current interrupt device, comprising: a) a first conductive plate, composed at least in part of aluminum, including: b) a second conductive plate, composed at least in part of aluminum, in electrical communication at a point of electrical contact with the essentially planar cap of the first conductive plate, wherein the second conductive plate defines at least one through-hole, whereby equalization of pressure between opposite sides of the second conductive plate is maintained without interference by the first conductive plate, and whereby higher pressure on a first surface of the first conductive plate facing the second conductive plate relative to a second surface of the first conductive plate will cause separation of the first conductive plate from the second conductive plate to thereby disrupt electrical communication at the electrical contact.
