A coupling element is provided for an electric switching device wherein the coupling element includes a first switching contact for opening and closing an electric contact by a second switch contact. The coupling element has an oblong winding body having two ends that are opposite in the longitudinal direction of the longitudinal axis thereof, wherein the first switch contact is arranged on one end. The coupling element furthermore includes a rotation body through which the winding body extends and that is provided for coupling to a drive to carry out a rotation movement by the drive, wherein the rotation body includes two sides of which one faces one end (of the winding body and the other faces the other end of the winding body.

An operating device for a disconnector includes a drive unit, a Geneva mechanism, and a wire. The drive unit includes a forwardly and reversely rotatable motor serving as a drive source for driving a movable contactor of the disconnector, a power source supplying power to the motor, and a first pulley connected to a rotary shaft of the motor, and is disposed apart from the disconnector. The Geneva mechanism includes a second pulley that rotates in the same direction as the first pulley with the rotation of the first pulley, and a driven wheel that is intermittently driven while the second pulley rotates and that is provided with a rotary shaft connected to the movable contactor, and is attached to the disconnector apart from the drive unit. Further, as a flexible rotational force transmission member, a wire is stretched between the second pulley and the first pulley.

A switch includes: a circuit breaker; a disconnector; a grounding switch; and a manipulator that drives the disconnector and the grounding switch. The manipulator includes: a motor; a plurality of drive pulleys installed on an output shaft of the motor; and a controller for controlling rotation of the motor. Each of the disconnector and the grounding switch includes a switching manipulator that performs a switching action according to rotation of a driven pulley. A wire for transmitting torque of the motor is stretched around each of the drive pulleys and corresponding one of the driven pulleys. Each drive pulley includes: a mover having a catch that engages with the output shaft; and a chuck having a mover and a driver, the catch being engaged with the output shaft in the engaged state. The controller exclusively brings one of the plurality of drive pulleys into the engaged state.
