    Patent number: 6323581
    Abstract: 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.
