Abstract
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.
