徴とするアクチユエータのポジシヨンスイツチ。 A contact connected to the high potential side via a resistor is slidably brought into contact with the outer surface of the shaft of the actuator, and the shaft is grounded, thereby changing the potential of the contact as the shaft moves. In the position switch configured to electrically detect the position of the actuator by moving the shaft, a high-resistance material layer made of a high-resistance conductive material is formed on a part of the sliding area of the contact on the outer surface of the shaft. An actuator position switch characterized in that the contact point and the shaft are brought into contact with each other directly or through a high-resistance material layer depending on the position of the shaft.
