This application discloses a motor drive of electrical apparatuses which drives medium and high voltage switch disconnectors, circuit breakers, disconnectors, and earthing switches. The disclosed drive includes a system of reduction transmissions including a worm transmission and a cycloidal transmission located in a common housing. The axis of the output shaft of the drive is situated centrically on the axis of a wormwheel of the worm transmission, in the axis of the output gear of the cycloidal transmission and in the axis of a revolving eccentric bush. The wormwheel of the worm transmission is mounted immovably on the revolving eccentric bush on which there is mounted rotatably a gear wheel of the cycloidal transmission whose output gear is coupled with a slidable bush of a disengaging coupling mounted on the free end of the output shaft of the drive.

An input detecting device includes: an input receiver configured to receive position input; a position detector included in the input receiver and configured to detect at least a position of the position input; a rotary portion rotatably attached to the input receiver and configured to move between a standby position spaced apart from the input receiver and an advanced position closer than the standby position to the input receiver; a rotation detectable portion configured to be rotated relative to the input receiver together with the rotary portion and whose position is detectable by the position detector; and a push detectable portion whose position is detectable by the position detector when the rotary portion is positioned at one of the standby position and the advanced position.

A connection verifier, including a collar, a circuit board non-rotatably connected to the collar, the circuit board including at least one terminal, a switch rotatably connected to the collar and arranged to contact the at least one terminal, the switch including at least one finger extending in a first axial direction, and an indication device arranged to activate when the switch contacts the at least one terminal.

The present disclosure provides a rotary switch. The rotary switch may comprise a fixing body, a rotating body disposed in the fixing body, a cover coupled to an upper portion of the fixing body, and a first elastic body positioned under the cover to contact a plurality of protrusions formed on the rotating body. The protrusions of the rotating body may protrude in a side direction and radial direction of the rotating body to improve a rotational operation feeling and the quality of a rotational sound.

A control system comprises sources of supply, in terms of power and in terms of control signals, capable of equally piloting each of the electric thrusters and further comprises a switching device capable of linking any one of the sources of supply to any one of the electric thrusters. The switching device comprises a rotary main roller divided into a number of angular segments comprising input and output conductive tracks and pre-wired electrical networks linking the input conductive tracks to the output conductive tracks of each angular segment, the pre-wired electrical networks associated with the different angular segments all being different and dedicated to different configurations for the piloting of the electric thrusters by the sources of supply.

A controller of a rotary switch receives, via a contact receiver, signals from a plurality of fixed contacts of a rotary switch that rotates a movable contact to connect the movable contact to any of the fixed contacts, and outputs a command based on the received signals. The controller of the rotary switch monitors a transition of an output code received from the contact receiver, and determines that a failure has occurred in the rotary switch when the transition of the output code does not match a transition pattern of the output code of the case where the rotary switch operates normally.
