Switch probes are particularly used for presence testing of components. They open or close an electrical connection between the inner and outer conductor after reaching a defined spring travel (switch travel).
Feinmetall offers different types of switch probes:
With these switch probes, the exact position of components or connector elements can be determined with little effort. Whereas conventional switch probes only have one switch point after a specific travel, these advanced switch probes have two switch points integrated at a defined distance.
Switch probes with a ball head have an integrated free-rolling ball as a contact element at the end of the plunger. This makes these probes insensitive to lateral forces and leaves no marks on the contact surface. Typical applications are the lateral presence detection of connectors in test modules or the detection of PCBs.
