ABSTRACT:
A contact sensor for detecting operation of a movable probe against force added by an object from any direction. The contact sensor has a movable probe which is supported in a cylindrical housing, a bridge, and only one set of electric contacts which are provided at center of the movable probe and the bridge and pushed each other by a spring provided in the housing. The movable probe comprises a hollow connector, a stylus which fixed at one end of the connector and extended from an opening of a cylindrical housing, and a flange which is provided at the other end of the connector. The flange is freely mounted on an annular fulcrum fixed on an inner wall of the housing so that electric signals are detected by a detector when the movable probe freely inclines at the fulcrum and the electric contacts operate due to pushing the stylus with an object from any direction.
