Abstract:
1. A compression actuating mechanism, by means of a rocking pushbutton, of electrical controls, comprising at least one fixed contact, with a contact holder connected to a corresponding terminal, and at least a corresponding movable contact, carried by an anchor installed movably on a support, which is electrically connected to a corresponding terminal, the mechanism comprising a pin placed between said rocking pushbutton and the movable anchor, and pushed against the said movable anchor by a compression spring working in compression so that rotation of the rocking pushbutton in either direction causes a corresponding rotation of the movable anchor and therefore the opening or closing of the electric circuit connected to said terminals, to bring said movable contact away from or toward said fixed contact, the pin acting on said movable anchor through an articulated head or joint, characterized in that said joint is shaped like a fork whose two branches are in contact with the movable anchor at points which are substantially symmetrical with respect to the centre of the anchor.
