ABSTRACT:
For a horizontal orientation of a switching-type probe head, force developing device is provided to compensate for a component (F.sub.1) of the gravitational weight vector (F.sub.g) of the deflectably movable part (11) of the probe head, the compensating force being perpendicular to the direction of loading the movable part (11) into its at-rest (undeflected) null position in the probe head. This force-developing device is illustratively a magnetic bearing (5, 6) which is operative without involving any added mechanically contacting action within the probe head.
