Claims

[Scope of utility model registration request]

It has an opening in which the vacuum valve can be stored on the back side and a deep groove in the upper wall, and a pair of support arms for pivotally supporting the operating lever of the vacuum valve are arranged in parallel on the outside of the upper wall, sandwiching the deep groove. In the insulating frame of a box-shaped vacuum switch made of synthetic resin molding and having mounting legs having mounting holes perpendicular to the front wall surface at the upper and lower ends of the front side outside the side wall, the upper wall of the support arm An insulating frame for a vacuum switch, characterized in that the mounting dimensions are reduced, each reinforcing leg is integrally formed parallel to the front wall and extending outward, and the reinforcing leg also serves as the upper mounting leg. .
