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 center ( 46 ). |
