摘要： The invention relates to a device for controlling an electrical appliance designed to be able to perform the following in succession: - during a phase of opening a moving contact, moving the connection end of the moving contact (2a) provided on an output member (2) from point P1 to point P2 under the effect of a mechanical opening spring (12) that sets in motion a moving abutment element (11) which, through butting against it, drives the output member (2); during a phase of resetting the spring, setting the moving element (11) in motion under the effect of a switching-on of a motor (8), keeping the end (2a) at the point P2; and - during a phase of closing the moving contact, moving the connection end (2a) from point P2 to point P1, again under the effect of a switching-on of the motor.
