A circuit protection device having a warning function includes a casing with a button, a first terminal and a second terminal connected thereto. A resilient bimetallic plate is connected between the two terminals and bends to be separated from the second terminal when overheat or overflow. A warning light is located within the button and connected to the first terminal. When the main circuit is connected, no current flows through the warning light which is not activated. When overheat or overflow, the bimetallic plate bends to cut off the main circuit and a connection member on the warning light is in contact with the second terminal to form a weak current circuit to light up the warning light.
