Abstract
A manually operated switch device for the control of electrical equipment, wherein the electrical elements of the switch are assembled in a housing and the mechanical elements are mounted on a body piece attached to the housing. At least one linearly transferrable slide member communicates with the body piece, the slide member having contact or guide surfaces adapted to cooperate with the stationary contacts. To the slide member is connected via at least one spring-type element, a power-spring-arming plate which is movable in parallel relationship with the slide member, in such a manner that during the movement of the power-spring-arming plate, the slide member is correspondingly moved under the force exerted by the power springs. By virtue of this arrangement, the switching phase always occurs in a consistent manner, irrespective of the speed used for rotating the switch operating lever.
