摘要： A linear actuator includes a casing and a retractable member driven by a motor is movably received in the casing and a contact member is connected to the retractable member. A first position switch connected to the motor, a plurality of travel switches and a final position switch connected with a diode are connected to the actuator. These switches are connected in series by normal-close switches. Normal-open switches of the travel switches located between the first position switch and the final position switch are connected to a circuit of the control device. The motor is stopped when the final position switch touches the contact member of the retractable member, the motor is activated, when a current is applied to the diode again.
