摘要（英）：

The utility model discloses an on-site isolation switch operation position indicator comprising a close-position contact switch and an open-position contact switch. The close-position contact switch and the open-position contact switch are respectively arranged at positions when the knife switch of an isolation switch is closed or opened. One end of the close-position contact switch and one end of the open-position contact switch are connected with a power supply. The other end of the close-position contact switch and the other end of the open-position contact switch are connected with the power supply through a close-position indicating lamp and an open-position indicating lamp respectively. The contact switches and the indicating lamps are utilized in the on-site isolation switch operation position indicator, so that the operation position of the isolation switch can be automatically displayed, on-site operators can visually and conveniently know the state of the isolation switch, and misoperation is prevented.
