Claims

[Scope of Claim for Utility Model Registration] (1) A driving piece that is swingably supported and fixed to a movable iron piece of an operating electromagnet and that engages with a movable contact rod of each of at least two or more vacuum valves arranged in parallel is attached. In a manual operation device for a vacuum electromagnetic contactor, the vacuum valve is connected and separated by rotation of an opening/closing shaft and a handle that is removably engaged with the opening/closing shaft. 1. A manual operation device for a vacuum electromagnetic contactor, comprising a rod-shaped manual operation handle having a through hole and a tip configured to be able to fit into the through hole. (2) The manual operating device for a vacuum electromagnetic contactor described in claim 1 of the utility model registration claim is characterized in that when the vacuum valve has three poles, the through hole of the movable iron piece is provided on the front side of the center pole axis. A manual operating device for a vacuum electromagnetic contactor.
