Rotating Test Probes

Rotating test probes (rotating probes) offer an alternative for the testing of assembled components under unclean conditions. When the plunger is pressed downwards, its special spiral design causes a rotation, limited to approx. 90°. This principle allows perfect contacting even when the contact surfaces are dirty or oxidised. In combination with the rotating motion, the tip styles – which are normally aggressive – also allow the use of springs with lower contact pressures.
