RS PRO 2.54 mm Pitch Spring Test Probe with Needle Tip, 3 A When it comes to safely testing out contacts in an electrical circuit, this pitch spring test probe is the perfect solution. Consisting of a spring, plunger and tubular barrel, the probe is designed to be wired into a receptacle, which can be housed. Having the probe and receptacle separated in this manner allows you to easily replace or repair it in case of damage. The probe is made from strong and resilient phosphor bronze material. Its gold-plated finish further enhances this and offers excellent conductivity for reliable testing. The product's 24.7 mm length means you can test contacts from a distance using its spring-loaded needle tip. This pitch spring test probe is typically used to test printed circuit boards (PCBs) and components. You can also use it to test batteries and consumer electronics devices like tablets or smartwatches.
