Rotating Test Probes

Rotating test 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.
