ABSTRACT:
The vacuum insulated switch includes a vacuum container; two stationary contacts contained in the vacuum container; two movable contacts contained in the vacuum container, each capable of contacting and separating from a corresponding one of the stationary contacts; a vacuum insulated actuating rod connected to the two movable contacts; an operating rod connected to the vacuum insulated actuating rod via a metal bellows; and a guide for guiding the operating rod. The vacuum insulated switch has an off-axis displacement allowing structure which is provided between the guide and the operating rod for allowing the off-axis displacement of the operating rod.
