A Switch Probe is a spring contact probe and receptacle combination that is normally open, and after a designated travel the switch probe closes. The most common use for switch probes is in the cable harness testing industry. The switch probe is used to verify the correct location of a terminal in a connector while checking the retention force as well.

Switch probes also verify the presence of nonconductive components such as caps for connectors or devices on a circuit board. SFENG probes can offer different standard sizes of switch probes.
