A service plug includes a lever (30) supported on a cover (20) for movement between full and partial locking positions. A housing (90) is connectable to and separable from the cover (20) as the lever (30) is moved. Heavy current terminals (50) are disconnected from a power supply circuit in a separating process of the cover (20). A detection terminal (60) is switched from an ON-state to an OFF-state in the separating process of the cover (20). A stopper (40) contacts restricting walls (25) on the cover (20) to stop a movement of the lever (30) from the full locking position toward the partial locking position until the heavy current terminals (50) are disconnected from the power supply circuit after the detection terminal (60) is switched from the ON-state to the OFF-state in the separating process of the cover (20).
