A rigid column and a suspension knee are combined in a probe held in assembly via its column. The suspension knee has a base arm laterally connecting at and propagating away from the column. The base arm extends up to a lateral knee extension where a reverse arm continues from the base arm back in direction towards a central axis of the column. The reverse arm terminates in a contact tip in a tip offset to the column axis that is smaller than the lateral knee extension. During application of a contacting force onto the contact tip, a first deflection of the base arm and a second deflection of the reverse arm counter act in conjunction with base and reverse arms' structural configurations. As a result, scrub motion may be well defined in direction and magnitude without need for additional guidance of the deflecting probe structure.
