在にしたことを特徴とする回路しや断器。[Claims for Utility Model Registration] A housing, an operating switch, an abnormal current detection device for detecting abnormal current in a circuit, a device that disconnects the circuit when an abnormal current is detected by the device, and operation of the operating switch. The basic structure is a trip mechanism that is equipped with a link connected to the rod and opens and closes the track in response to the swinging motion of the link, and a rocker type switch or a push button type switch is installed as the switch for the housing. The mounting dimensions of the switches with respect to the housing are set to be the same so that they can be attached and detached at any position, and the rocker type switch is provided with an operating rod that swings in accordance with seesaw movement of the operating handle, and the push button switch is An operating lever that includes two push buttons and a cam mechanism that rotates in opposite directions when each push button is pressed, and further swings in the same trajectory as the operating lever of the Rocker type switch in response to the rotational movement of the cam mechanism. A circuit breaker comprising: an operating rod of the rocker type switch and an operating rod of the push button type switch can be freely connected to the link.
