摘要： A plug with security device, including a housing, several conductive insertion plates adapted to be inserted into a power socket, conductive wires connected to an electric appliance and a security device. The insertion plates are connected with the conductive wires in the housing. The security device is disposed between at least one insertion plate and one conductive wire and includes a casing, a disconnector seat disposed therein, a thermal bimetal blade disposed on the disconnector seat, a movable contact disposed on the bimetal blade, a fixed contact disposed in the casing and connected with the conductive wire to naturally contact with the movable contact, and an insulative separating structure. When an excessively large current passes through the electric appliance, the bimetal plate is bent to separate the movable contact from the fixed contact and open the circuit. At this time, the insulative separating structure is inserted into a space between the movable and fixed contacts so as to keep the circuit open.

摘要： A titterboard type switch with security structure, wherein a relay unit is disposed between two terminal legs connected with power wires and an electrothermal conductor is connected between the relay unit and one of the terminal legs, whereby when powered on, the electrothermal conductor is slightly heated and in the case of overload, the electrothermal conductor creates high temperature. The relay unit is disposed with a resilient movable contact pushable by a sliding member for controlling whether the movable contact contacts with the other terminal leg or not. The sliding plate is pushed by a swinging plate which is shifted by a push button via a linking unit. A bimetallic plate is disposed between the electrothermal conductor and the swinging plate, whereby when the electrothermal conductor creates high temperature due to overload, the bimetallic plate is deformed to release the movable contact from pressing force of the swinging plate, whereby the movable contact is resiliently restored to a power cut state to ensure safety from overload.
