Abstract

A safe switch structure includes a main body, a button, a switch component and an alloy chip. The upper part of the main body is hinged with the button. The lower part of the main body is provided with a combination of at least two conducting plates. The switch component is hinged with the second conducting plate. Taking the second conducting plate as a supporting shaft, both ends of the switch component swing up and down like a rocker. One end of the alloy chip is fixed on the first conducting plate. When in the normal state of use, the button is pressed down and the button convex component presses against both ends of the switch component, which swing up and down and separate from or contact with the alloy chip, forming power-down or power-on. In case of over-current in power-on state, the alloy chip is heated and deformed for free tripping in opposite direction and the alloy chip separates from the switch component, forming power-down state. When the button is pressed down again, the convex component of the button will move to press against the other end of the switch component to move the switch component to the position of original power-down state. When the temperature drops, the alloy chip will rebound in opposite direction to the normal use state, thus guaranteeing safe use of electricity.
