Abstract:
1. An apparatus comprising: an electronic device; an electrical contact; a circuit protector that at least partially defines a conductive path from the contact to the electronic device; wherein the conductive path includes a first conductive member and a second conductive member; wherein the circuit protector includes an active material that is one of shape memory alloy and shape memory polymer, that contacts the second conductive member, and that is configured to undergo a change in at least one attribute in response to an activation signal; wherein the second conductive member is selectively movable between a first position in which the second conductive member is in contact with the first conductive member, and a second position in which the second conductive member does not contact the first conductive member; and wherein the circuit protector is configured such that the change in at least one attribute causes the second conductive member to move between the first and second positions.
