ABSTRACT:
A memory actuator is provided for a rearview mirror system having a reflective element and a controller. The memory actuator includes a housing and at least one positioning member extending from the housing to move the reflective element about at least one degree of freedom. At least one motor is provided for driving the positional member. A linear position transducer having a body is provided for coupling to the reflective element and a circuit board is positioned in the housing. The body of the linear position transducer is guided at the circuit board in at least one direction and moves alone the circuit board between a plurality of positions in response to movement of the reflective element about the at least one degree of freedom. The circuit board is configured to generate a signal to the controller as a function of the position of the body of the linear position transducer along the circuit board.
