H01H31/00—Air-break switches for high tension without arc-extinguishing or arc-preventing means
H01H31/14—Air-break switches for high tension without arc-extinguishing or arc-preventing means with bridging contact that is not electrically connected to either line contact in open position of switch
H01H31/16—Air-break switches for high tension without arc-extinguishing or arc-preventing means with bridging contact that is not electrically connected to either line contact in open position of switch with angularly-movable bridging contact or contact-carrying member
H01H31/18—Air-break switches for high tension without arc-extinguishing or arc-preventing means with bridging contact that is not electrically connected to either line contact in open position of switch with angularly-movable bridging contact or contact-carrying member actuated through the movement of one or more insulators
H01H31/20—Air-break switches for high tension without arc-extinguishing or arc-preventing means with bridging contact that is not electrically connected to either line contact in open position of switch with angularly-movable bridging contact or contact-carrying member actuated through the movement of one or more insulators at least one insulator being rotatable about its own geometrical axis
