INTERRUPTER SWITCH ARRANGEMENT ABSTRACT: Disclosed is a switch suitable for use in power systems. The switch is of the vertical break type, having two stationary support insulators and one reciprocatory, insulative push rod, wherein movement of a switch blade takes place in a plane which also includes the insulators and the push rod. The two insulators are mounted on a base, one insulator sup- porting a switch blade hinge assembly, and the other insulator supporting a contact assembly for the switch blade. A novel linkage mounted to the hinge assembly connects the blade to the push rod and permits at least 90° of movement of the blade without adversely affect- ing dielectric clearances between the push rod and the insulators. The insulators remain stationary when the switch operates, only the push rod and the novel link- age moving to provide motive force to the blade. The push rod may be reciprocated by interconnection to a rotatable shaft via a lever. The shaft may be con- nected to an operating pipe reciprocated by a remote operator for rotation therewith. After the switch is open, the novel linkage permits the push rod and the lever to form an over-center toggle which, together with the more than 90° opening of the blade, prevents the blade from inadvertently moving toward engagement with the stationary contact as a result of external forces such as wind, etc. The switch and the linkage are usable in single pole and polyphase switches in a variety of configurations.
