Abstract
In a switching multicoordinate probe an accurate and accurately reproducible switching behavior is achieved by a plurality of bearing points, which all have the same elasticity. The bearing balls (14) and their countermembers (17) exhibit a sufficient number of degrees of freedom, in order to be able to accurately orient themselves with respect to each other during installation. After adjustment the contact zones of the individual bearing balls (14) with the inclined sectional surface (18) of their countermembers (17) form an accurate bearing arrangement for the probe retainer (10), which bearing arrangement lies in a plane prependicular to the stylus access (FIG. 1).
