Abstract
An overheating destructive disconnecting method for switch, which enables a first elastic force to concurrently apply force to an overheating destructive member and a movable conductive member. Moreover, the force direction causes the movable conductive member to concurrently contact a first conductive member and a second conductive member to form a conductive circuit. A second elastic force acts on the movable conductive member, and the force direction thereof causes the movable conductive member to separate away from the first conductive member or the second conductive member, The overheating destructive member is positioned in a required non-electric transmission path and at a distance from the movable conductive member. When the overheating destructive member is destructed or deformed under a fail temperature condition, the first elastic force is lessened or lost, at which time the second elastic force causes the movable conductive member to change position, thereby breaking the current-carrying circuit.
