PROBLEM TO BE SOLVED: To keep a lever at a wanted rotational position for good workability when engaging one connector housing with the other connector housing. SOLUTION: Related to a lever engagement type power-source circuit breaker 1A, a lever 2 is movably provided to one connector housing 1. A cam groove 21 is provided to the lever 2 while a cam pin 36 is provided to the other connector housing 3. When the lever 2 is moved from a moving start position to an engagement completion position, the cam pin 36 is guided by the cam groove 21, so that one connector housing 1 approaches the other housing 3. Thus, terminals 9 and 35 of both connector housings 1 and 3 contact with each other. The lever 2 is provided with a first locking hole 22 and a second locking hole 23. One connector housing 1 is provided with a locking projection 12, and the lever 2 is held at the moving start position and the engagement completion position.
