A small-sized simple switch for circuit protection of the present invention is simple in structure and easy to operate, and can be readily switched for safety protection of circuits. An alloy plate of the present invention is highly resilient. When in overload, the alloy plate expands and becomes deformed due to the different thermal expansion coefficient and is deformed upward to become disengaged from a wire connecting pad with which it is originally in contact, causing the switch to be switched from the "ON" condition to the "OFF" condition. The alloy plate pushes a lever pivoted to the moving end of the alloy plate to move up such that the lever pushes one end of a pivoted reset button to move up. A user only has to depress the reset button and the switch will be again in the "ON" condition such that repeated ON / OFF conditions of the protection circuit can be effected. If there is no overload on the circuit, the switch of the present invention will be operated to be in "ON" or "OFF" condition as ordinary switches.
