Add text.

Claims

[Claims for Utility Model Registration] (1) A device for checking whether a main movable contact constituting a main contact of a switching device has reached a predetermined position during the opening/closing operation of the switching device, which a compression chamber in which fluid is compressed by the movement of the contact at the terminal end portion of the contact during its movement stroke; a conduit connected to the compression chamber; and a conduit disposed in the conduit from the compression chamber to the conduit. an object that vibrates due to the flow of fluid flowing into the opening/closing device, the switching device comprising: an object that vibrates due to the flow of fluid flowing into the switching device; Operation confirmation device. (2) In the device set forth in claim 1 of the utility model registration claim, the object that vibrates due to the flow of fluid is
1. An operation confirmation device for switching equipment, characterized in that the main movable contact is arranged at the terminal end in the opening direction and the terminal end in the closing direction of the movement stroke of a main movable contact, and vibrates differently from each other. (3) Utility Model Registration The device according to claim 1, wherein the vibrating objects arranged in different phases of the switchgear vibrate differently from each other.
