装置。[Claims for Utility Model Registration] First and second switching devices each having a handle for manual operation and provided on the first and second low-voltage lines, respectively, and a second switching device connected between the load-side terminals of both switching devices. A low voltage circuit switching device comprising three switching devices, and forming a mechanical interlock that allows turning off any one of the three switching devices to turn on and off the other two. The interlock device includes a key plate that mechanically prohibits the on-operation of the handle, and by inserting a key, the key plate can be operated to inhibit or release the prohibition, and the key is activated only when the key plate is in a prohibited operation state. A key block that can be pulled out is provided for each of the switches, and 3
An interlock device for a switching device for a low voltage circuit, comprising only two keys for each key block.
