Claims

[Scope of utility model registration request]

(1) In a grounding switch for grounding an electric circuit housed in a grounding case filled with insulating gas, the movable contact or the part that opens and closes integrally with the movable contact is placed in the open or closed circuit position. Mark the location.
A grounding switch that has a window in a position where the above mark can be visually seen from the outside of the grounding case, and is configured so that the closing position of the movable contact, or the closing position and the opening position, can be visually inspected and confirmed. .

(2) A plate is provided that clearly indicates the position tolerance range indicating that the opening/closing operation is complete, corresponding to the mark provided on the movable contactor or the part that is integrated with it for opening/closing operation, and a plate is provided for each opening/closing position. The earthing switch according to claim 1, wherein the earthing switch is constructed so that the mark and the allowable range of the plate can be visually checked through a window to check the relative softness.

(3) A mark provided on a part that opens and closes integrally with a movable contactor; the mark indicating the opening position and the mark indicating the closing position are separated by color. The earthing switch described in paragraphs 1 and 2.
