<P>PROBLEM TO BE SOLVED: To provide a control panel having a simple configuration eliminating the need for arranging a monitor switch for door to each door. <P>SOLUTION: The control panel has a plurality of doors closing an opening section for a box body, electrical locking mechanisms controlling the opening and closing of the door and a breaker electrically conducting and interrupting a power supply, and permits the electrical conduction of the power supply only when a plurality of all doors are closed. In the control panel, the breaker has an external interrupting mechanism incorporated into the breaker, and keys fitted to the locking mechanisms are fitted to one of the sides of doors mutually abutted when the adjacent doors in a plurality of doors are closed. In the control panel, the locking mechanisms fitting the keys with control means controlling the pulling-out of keys when the power supply is conducted electrically and mounting/demounting monitor means monitoring the mounting and demounting of keys are fitted to the sides of the other doors, the mounting/demounting monitor means are connected electrically to the external interrupting mechanism for the breaker and the electrical conduction is permitted only when the keys are fitted to the locking mechanisms. <P>COPYRIGHT: (C)2009,JPO&INPIT |
