What is a test probe?

Test probe – test pin – spring probe – pogo pin. These are all generic terms to describe a component whose spring loaded tip will provide a reliable electrical contact to a target whose distance away may well be variable or indeterminate.

The traditional use for them is to make contact with printed circuit boards (PCBs) or electrical components, in order to test functionality and to measure the value of the components. They are widely used in vacuum test fixtures associated with automatic test equipment (ATE). They are also used inside a functional test station as part of a larger production line.

The general purpose test probes in the three sections below can be used in a wide variety of test applications such as in test jigs and test fixtures.
