Gold Plated Switch Probe Test Pogo Pin SWP260 Series for Connection Switch probes are a kind of functional probes. They are used to determine the correct location of a terminal in a connector. They can also be used to determine the presence of nonconductive components, etc. Their application field is mainly as below Wire harness connector PCB component detection Door open-close switch Fixture component detection Automation process sensing Position and retention force Below switch probe we will introduce is SWP260. Its diameter is 2.6 mm and total length is 39.6 mm. As usual, switch probes do not entail very high currents, and this model SWP260 can work with the current up to 3 A. The typical maximum contact resistance of this model SWP260 is 50 mΩ. The materials used for the construction of switch probes are different for each component: The barrel is made of brass. Subsequently nickel plated during the galvanic plating phase. The spring is made of gold plated music wire. The plunger is made of BeCu, then gold or nickel plated. The insulating sleeve is made of POM For details of SWP137 switch probe, please check below parameters. Technical Specifications Recommended Current Rating: 3 Amps, continuous Contact Resistance: 50 milliohms, maximum Full Stroke: 5 mm Rated Stroke: 3.5 mm Spring Force: 130 gf (4.5 oz) Normal Condition: Continuity between Plunge 1 and Plungert 2 Press down 0.7 mm: Disconnecting between Plunger 1 and Plunger 2 Materials Contact Barrel: Brass, Nickel Plated Spring: Music Wire, Gold Plated Plunger 1: Beryllium Copper, Gold Plated Plunger 2: Beryllium Copper, Gold Plated Insulating Sleeve: POM For more information, please check below catalog.
