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).
L'invention concerne un mécanisme permettant d'actionner par pression, au moyen d'une touche basculante, des éléments de commande électriques tels que des interrupteurs, des commutateurs, des sélecteurs et analogues. Ce mécanisme comporte au moins un contact fixe (12) et un contact mobile (11), portés par un élément de fixation mobile (10), pouvant être tourné pour éloigner ou rapprocher le contact mobile (11) du contact fixe (12), par l'intermédiaire d'un axe (21) actionné par la touche basculante (5) et pressé contre ledit élément de fixation mobile (10) par un ressort de pression (22). L'axe agit sur l'élément de fixation mobile (10) au moyen d'une tête ou d'un élément de transmission (38) articulé(e) en forme de fourche, de sorte que les deux branches de la fourche se placent d'elles-mêmes sur des zones (45) correspondantes de l'élément de fixation qui sont sensiblement symétriques par rapport à son centre (46).
