A switch structure comprises a control element, which comprises an alloy piece and a swinging device. The swinging device has an actuating element used to actuate the swinging device when the actuating element is pushed. When the alloy piece is overheated due to overloading of current, it will deform toward the actuating element so as to eject the actuating element, which causes the swing device to swing outwards and is released from the supporting of the stopper in the switch body. Then, the swing device moves towards the original closing position, and the elastic contacting piece is released from the pressing of the swing device to eject upwards. Two joints connected in an electric loop are tripped. The object of rapid response, cutting power source, and safety is therefore achieved.
