ABSTRACT:
The feeler comprises a stationary support (1) and a movable support (4) provided with a tip (5), which are pressed against each other by a spring (21). The immobilizing of the movable support with respect to the stationary support is obtained by a system of connections with zero degree of freedom formed of four spherical positioning pieces (7 to 10) applied, by six contact points, to six inclined resting surfaces (15 to 20) with flat contact surface, two first pairs (15-16, 17-18) of which are convergent and arranged respectively under two first opposing positioning pieces (7, 8) and the last two of which (19, 20) are parallel and each arranged under one of the two other opposing positioning pieces (9-10). An electrical circuit is provided to detect any interruption of contact between at least one positioning piece and one resting piece signifying an encounter of the tip (5) with the object.
