Claims

[Scope of utility model registration request]

(1) First and second fixed contacts, each connected to a different electrical circuit, movable shaft-supported contacts that can be switched into and out of each of the first and second fixed contacts, and connected to a common electrical circuit. A double-throw disconnector is provided with a contact, and an opening/closing shaft connected to the movable contact via an insulated operating rod and rotatably supported by a frame, wherein the first and second of the movable contact
In a device equipped with three auxiliary switches that display engagement and separation with the fixed contact and intermediate positions, the device is capable of engaging with each of the two auxiliary switches corresponding to the first and second fixed contacts. first and second operating levers supported by a spring and biased by a spring in the anti-engagement direction; and a shaft of the opening/closing shaft supported pivotally so as to be lockable with an auxiliary switch for indicating an intermediate position of the movable contact. a third operating lever comprising a concave arc wall concentric with the core and having a recess and biased by a spring in the engagement direction; and each of the first and second operating levers fitted on the opening/closing shaft. The movable contact has first and second cranks that engage in a predetermined position to operate the auxiliary switch, and that roll on the concave arc wall of the third operating lever and engage in the concave part. 1. A movable contact position display device for a double-throw disconnector, comprising: a drive crank set having a roll crank for operating an auxiliary switch for indicating an intermediate position of a double-throw disconnector.

(2) Utility Model Registration In the device set forth in claim 1, adjustment bolts that can move forward and backward are screwed into each of the first and second cranks to determine the engagement positions with the first and second operating levers. A movable double-throw disconnector characterized in that the third operation lever is provided with an adjustment plate so that the engagement position with the auxiliary switch for indicating the intermediate position of the movable contact can be adjusted. Contact position indicator.
