Abstract
Mécanisme anti-rebond pour la commande de commutateurs électriques. Les commutateurs électriques tels que 48 sont actionnés par l'intermédiaire de mécanismes sélectionnés mobiles tels que 19, agissant sur des bras de commande 47 des commutateurs. Lors du retour en position de repos des mécanismes 19 et de l'ouverture des commutateurs 48, un mécanisme universel 77 empêche le rebond du commutateur. Mécanisme applicable notamment à la commande des commutateurs de codage de caractères dans un clavier de machine à écrire ou analogue.
