Motor actuator with air-mix door opening-limiter and built-in switching unit

摘要: A motor actuator for use in an automobile air-conditioner actuating air-mix door, includes electric circuit controlling the rotational speed of a depending on various conditions such, example, as vehicle compartment temperature, and mechanical limit switch limiting or restricting extent angular movement limitation door. According to preferred embodiment, built-in switching unit having disposed first housing producing control signals components air-conditioner, second are detachably assembled together by locking lug mating retainer recess.
