CA 2283475

An electrically controlled actuator comprises at least two co-planar blades formed by a U-shaped pressing from a sheet of material. The end of one blade (60) is used as a mounting for the actuator and the end of the other blade (85) is used as an actuation surface. Piezo ceramic material is fixed to opposite surface of the two blades in order to flex the actuation surface with respect to the fixed surface. An electrically relay or residual current device incorporating such an actuator is disclosed.

L'invention concerne un actionneur commandé électriquement qui comprend au moins deux lames coplanaires formées par emboutissage d'une tôle en U. L'extrémité d'une des lames (60) est utilisée comme monture pour l'actionneur, l'extrémité de l'autre lame (85) servant de surface d'actionnement. On fixe un matériau piezo-céramique aux surfaces opposées des deux lames afin de faire fléchir la surface d'actionnement par rapport à la surface fixe. L'invention concerne un relais électrique ou un dispositif à courant résiduel intégrant cet actionneur.
