ABSTRACT:
A touch probe is provided with an arm coupled to a movable arm-set and supported in a casing. The touch probe includes an electric switch with a housing fixed to the casing, and a mechanical transmission device for mechanically transmitting displacements of the arm, and causing the disengagement of a conductive small ball from two stationary conductive bars, thereby opening an electric detecting circuit. An elongate mechanical body of the mechanical transmission device includes a spherical-shaped element that is transversally urged against a guide surface, having at least a binary surface, for guiding with accuracy and free of clearances the displacements of the elongate mechanical body. A bent flat spring contacts a plane portion of the spherical transmission element for achieving both transversal thrust against the guide surface and the antirotation of the elongate mechanical body.
