Abstract
An overheating destructive disconnecting method for switch, whereby an operating member applies a first elastic force under normal conditions to enable the movable conductive member contacts a first conductive member and a second conductive member to form a conductive circuit; and a second elastic force to enable the movable conductive member to separate from the first conductive member or the second conductive member. The installation position of the overheating destructive member is used to receive heat energy instead of allowing current to flow thereto. When the overheating destructive member is destructed or deformed under a fail temperature condition, lessening or loss of the force applied by the first elastic force towards the movable conductive member causes the movable conductive member to no longer allow electrical conduction to the first conductive member and the second conductive member, thereby breaking the current-carrying circuit.
