ABSTRACT:
In a switching multi-coordinate probe an accurate and accurately reproducible switching behavior is attained by a plurality of seating points, which all have the same elasticity but also a relatively high stiffness. The bearing members (14) and their counterbearing support members (16) exhibit an adequate number of degress of freedom, in order to be able to accurately align themselves with respect to each other during assembly. After adjustment the contact zones of the individual bearing members (14) form with their counterbearing support members (16) circular lines, which all lie in one plane with respect to the stylus axis (FIG. 1).
