Amendment August 23, 1983 The name of the invention is amended as follows. Title of the invention Monitoring device for electronic lock for switch The scope of the utility model registration claim and the brief description of the drawings are amended as follows.

[Scope of claim for utility model registration] A locking control that determines whether a code number input from a key switch matches a registration number registered in advance and allows the switch to be operated by operating a forward/reverse and stop operation switch. The electronic lock for a switch is provided with a monitor corresponding to each of the operating switches, and the locking control section includes:
1. A monitor device for an electronic lock for a switch, characterized in that a monitor operation control means is provided for displaying and operating each monitor in accordance with the operation permissible state of each operation switch.

In the figure, 1 is a digital key, 3 is a switch, 8, 9
is the operation indicator lamp, 10 is the power indicator lamp, 11
, 12 and 13 are push button switches.

Claims (1)

[Claims for Utility Model Registration] (1) A key switch means for digitally inputting a PIN number, and a number for determining whether the input number from the key switch means matches a registration number registered in advance. The determining means receives an output signal when the input recited number from the number determining means matches the registration number, and outputs an operation permission command to a switch operation switch mechanism that selects forward/reverse drive of the switch. The unlocking commanding means is further provided with an unlocking command means for restricting the operation of the switch operation switch mechanism to a predetermined time or a predetermined number of times after the output of the operation permission command. A digital locking switch device for a switch, characterized in that the device is provided with an opening/closing operation restriction means for returning the switch to the locked state thereafter. (2) The utility model registration claim 1 is characterized in that the opening/closing operation limiting means limits the number of operations of the switch operation switch mechanism to one within a predetermined number of times. Digital lock switch device for switches.
