(54) Control mechanism for an electrical switch


(57) The invention relates to an electrical switch control mechanism (1), comprising a rocker arm (2) and a control element (3), which is movable between two transition positions, a first (A) and a second (B) transition position, by means of the rocker arm, the electric current being adaptable to pass through the control element from one contact terminal (5; 51, 52, 53) to the other at least in one of the transition positions. The rocker arm (2) and the control element (3) have in association therewith a spring (7), specifically a coil spring, which is set between the rocker arm and the control element, such that the control element is pressed by the spring either to the first (A) or the second transition position as the rocker arm is pivoted with respect to a mid-position and a pivot axis (D-D) over to the first or second side, respectively.
