ELECTRICAL SWITCH
An electrical switch has a casing, fixed contacts and at least one moving contact located in the casing, and a rotor supported in the casing for rotation about an axis of rotation to move the moving contact into and out of contact with at least one of the fixed contacts. There is also an operating mechanism for rotating the rotor. The fixed contacts are arranged on one side of the rotor with respect to the axis of rotation.
EFFORT TRANSMISSION MODULE
A module for transmission of a force including two toothed wheels which are connected to a main shaft; a first ratchet holder and a second ratchet holder which are provided with a first ratchet and a second ratchet, and are designed such, when they are actuated, to rotate the toothed wheels by support of the ratchet concerned against a tooth of the toothed wheel; a first cam and a second cam, which are designed to actuate respectively the first ratchet according to a first angular course around an axis YY of the first cam, and the second ratchet according to a second angular course around the axis YY of the second cam, which is different from the first angular course.
High-voltage switch for series/parallel applications and tap changer applications
A switch includes an insulating base having an upper surface and an assembly having a mounting surface. The assembly configured to be arranged on the insulating base, the assembly having a lower surface, the assembly being configured to be arranged on the upper surface of the insulating base with an open space between the lower surface of the assembly and the upper surface of the insulating base. The switch further includes a plurality of fixed contact units mounted in an aligned arrangement on the mounting surface of the assembly and a movable contactor mounted to move within the bore of the insulating body and the electrical contacts of the plurality of fixed contact units.
VIBRATION-TOLERANT MULTI-POSITION, MULTI-POLE CONTINUOUS-ROTATION STEPPER RELAY
Apparatus and associated methods relate to sequentially opening and/or closing a plurality of switches. A rotational securing assembly sequentially secures and releases a plurality of indexing members evenly distributed along a circular path centered on an axis of rotation of the rotatable disk, thereby sequentially securing and releasing the rotatable disk to and from a sequence of rotational positions. A ratcheting assembly sequentially engages a plurality of advancing members of the rotatable disk, thereby sequentially rotating the rotatable disk to a next one of the sequence of rotatable positions. A cam coupled to the rotatable disk sequentially either opens or closes a plurality of switches attached to an annular frame and distributed along a second circular path centered on the axis of rotation. Operations of the rotational securing assembly are coordinated with those of the ratcheting assembly so as to advance rotation of the rotatable disk in a stepwise fashion.

Control device of the spring type particularly for a high-voltage or medium-voltage circuit breaker or switch
The control device possesses a rigid main part combining most of the functional elements of this type of control device. It is made up of two portions of a rotary shaft, having placed between them a cam and a support arm that are connected together by a pivot that is offset relative to the axis of rotation. A toothed wheel having an inner set of teeth is placed around the support arm that is provided with a rachet system. The toothed wheel has an outer set of teeth-driven by a motor, via an intermediate gearwheel. The pivot controls the compression of the actuator spring by the assembly rotating. The device is applicable to high and medium voltage circuit breakers and switches.
