The present invention provides a power source breaker which can forcedly and surely isolate a power supply circuit in case of abnormalities such as short circuiting of a wire harness, collision of road vehicles, and also has a structure suitable for miniaturizing itself. Only by changing a rotation angle of the rotary axle 19 on the lock 18 which is assembled rotatable around the central axis of a rotary axle 19 along a plane perpendicular to the sliding direction of said shaft 16, both constraining the shaft 16, pushed by said release spring 17, at the initial position where a pair of the terminals 15a, 15b intervened in a power supply circuit is set in the connected state with each other and moving the shaft to the isolated position where a pair of the terminals 15a, 15b intervened in the power supply circuit is set in the released state.
