ABSTRACT:
A feedback apparatus for a vehicle air-conditioning actuator is provided. The feedback apparatus includes a cover plate including a thin plate resistor formed on the bottom thereof, a small case combined with the cover plate, including an assembly protruding portion formed in one side thereof, a plate-shaped rotation slider interposed between the cover plate and the small case, including a third axial hole and an opening whose size is about a quarter of the total size, a wiper whose contact front end is exposed in the opening of the rotation slider and rear end is fixed to the bottom of the rotation slider to rotatably contact a thin plate resistor formed on the bottom of the cover plate, a terminal assembly having connection pins for receiving external signals in which connection pins combined with the cover plate is formed. Since a contact between the wiper and the thin plate resistor is accomplished in a sealed case, there is little possibility of altering an initial set position due to an external shock. Thus, an operational stability of the actuator is enhanced.
