PROBLEM TO BE SOLVED: To provide a magnetic sensor switch turning on/off an electric contact by allowing a magnetic sensor to respond to approach of a magnet. SOLUTION: The narrow, long, and cylindrical magnetic sensor having opposed magnetic poles in the both ends is attached thereto so as to clockwise and counterclockwise turn, and an auxiliary magnet is provided in a region outside the rotation radius of the magnetic sensor near one of the magnetic pole and provided with a displacement force retaining the magnetic sensor in a position rotated by a prescribed angle. A movable contact piece is attached to the magnetic sensor and, when the magnetic sensor turns, the movable piece is turned so that one of contacts of the movable contact piece is brought in contact with one of a pair of fixed contact pieces oppositely disposed to the respective contacts.
