摘要： A switch for power lines which is actuated by a supporting rotatable insulator. A first insulator has a bearing at each end, one to be attached to a support such as a pole, and the other to the conductor of the power line. The first insulator is freely rotatable without moving the conductor. A second insulator structurally interconnects two segments of the conductor, and a movable switch blade movable by rotation of the first insulator connects or interconnects the segments. This invention makes possible the innovation of remotelyactuated group operation of a plurality of in-line switches, in addition to its capability of individual operation of a single switch.

摘要： An isolator switch for high voltage transmission lines and switch yards. A switchblade is rotatably mounted to a bearing which bearing is rotatable around a central axis. The switchblade can be swung in a plane normal to the central axis independently around the bearing, and also around the central axis by rotation of the bearing around the central axis. A contact member is spaced from the central axis, and exposes a contact surface to the switchblade. A circuit is completed by the combined motions of turning the switchblade around the bearing and turning the bearing around the central axis, so as to move the switchblade against the contact surface in an abutting relationship which may be either compressive or sliding, there being a substantial longitudinal movement of the tip of the switchblade along the line joining the contact surface and the central axis, this being a toggle-type motion. Preferably the contact surface is inside a cavity whose walls will restrain the tip of the blade from lateral disengagement after the contact is made. The contact member and also the switchblade may be mounted to a column which permits deflection in response to force exerted between them, and which also renders the conductive portion of the switch nonresponsive to earthquake motion. According to a preferred embodiment, the device is provided with a pair of such switchblades whose angular positions relative to the central axis are angularly coordinated.
