<p>A mechanism is described for compression actuation, by means of a rocking key, of electric controls such as switches, change-over switches, selector switches and the like, in which there are provided at least one fixed contact (12) and one movable contact (11), carried by a movable anchor (10), rotatively actuated to bring the movable contact (11) towards or away from the fixed contact (12), through a pin (21) operated by the rocking key (5) and pushed against said movable anchor by a compression spring (22), where the pin acts against the movable anchor (10) by means of an articulated head or joint (38) shaped like a fork, so that the two branches of the fork arrange themselves on corresponding areas (45) of the anchor that are substantially symmetrical with respect to its centre (46).</p> |
