Abstract

Electrical switching device, characterized by comprising: (a) a housing having therein mounted means of contact; (b) an actuator member, pivotally mounted within said housing for limited rotational movement, about a given point; (c) a contact support structure, supported by said actuating member, including said contact support structure, a support link, pivotally mounted on said actuator member, a mobile contact means, pivotally mounted on said support link for contact with said means stationary contact, and means arranged and adapted to provide relative engagement between said actuator member and said contact support structure in a position different from the pivotal connection between said actuator member and said support link, during a portion of the rotational movement of said actuator member ; y (d) elastic means for forcing said contact support structure and said actuator member to a predetermined normal position, said elastic means being operative for procuring force components in parallel and normal directions to the contact line between said moving contact means and said stationary contact means, so that the movement of said actuator member being absent, said relative engagement between said actuator member and said contact support structure is operative to cause a positive tangential movement between said movable and stationary contact means, whose tangential movement is stopped by said relative engagement to cause the movement of said contact support structure and of the mobile contact means supported thereby, in unison with said actuating member around said given point.
