Dispositif de commutation électromagnétique permettant de produire des commutations rapides. L'entrefer entre les deux pièces polaires (10, 11) d'un électro-aimant (12) comporte un aimant permanent (17). Face à cet électro-aimant (17) se trouve un induit (18) librement mobile dans l'entrefer (19) extérieur. L'aimant permanent (17) renforce l'effet dynamique exercé sur l'induit (18) après excitation de l'électro-aimant (12). Pendant la désexcitation de ce dernier, le champ magnétique (23) de l'aimant permanent (17) accélère la diminution du champ magnétique et par là même également la réduction de l'effet dynamique exercé sur l'induit (18). Le dispositif de commutation électromagnétique convient particulièrement pour des opérations de commutation rapides. Il est particulièrement indiqué pour être utilisé dans des soupapes injectrices de carburant d'un moteur à combustion interne.
