Abstract
Disclosed are a linear actuator control circuit capable of achieving accurate positioning, and a linear actuator. The control circuit comprises a motor driving circuit, a master control circuit and at least one intermediate switch; by disposing the intermediate switch between two ends of a stroke of the linear actuator, the intermediate switch can be triggered when the linear actuator runs to the intermediate switch; after the master control circuit receives information of the intermediate switch, running of the linear actuator is stopped, so that the linear actuator stops running when accurately running to a state that the intermediate switch is triggered, and then, accurate positioning of a sliding block on the linear actuator is achieved.
