Abstract

Improvements in electrical switching devices that govern alternative maneuvers, of the class of which comprise a contact chamber within which there are two contacts or groups of fixed and mutually spaced contacts, and a movable connecting member, provided with contacts suitable for entering into electrical connection with the fixed ones, associated with means of intermittent operation from a rest position to a connection position, characterized essentially by the fact that it constitutes the connection rod movable by a rocker-like part at whose ends there are contacts corresponding to the two circuits or groups of circuits of alternative operation, said rocker being guided by a guide formed inside the contact chamber so that it is movable in a direction perpendicular to the plane containing the fixed contacts and elastically requested to a position of rest, provided with a premiere of actuation opposed to these elastic and wedge-shaped biasing means to which a drive projection is confronted, formed in a control member that is guided in the same direction and connected with the intermittent drive means, the a rocker movably also transversely within the guide for locating the wedge on opposite sides of the driving shoulder, and being provided with support points on opposite sides, one of which is applied in oscillation and sliding against the flank of said guide located on the same side of the shoulder against which the wedge engages, to move said rocker to the opposite side of each driving maneuver.
