Test Probe Pogo Pin SWP300 for Electronic Test

Test Probe Pogo Pin SWP300 for Electronic Test

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 SWP300-C-460-3.5R(S). The diameter is 3 mm and total length is 46.2 mm.

As usual, switch probes do not entail very high currents, and this SWP300 test probe pin can work with the current up to 3 A. The typical maximal contact resistance of this test probe is 50 mΩ.

The materials used for the construction of switch probes are different for each component:
The barrel is made from brass. Subsequently nickel plated during the galvanic plating phase.
The spring is made of music wire plated with nickel.
One plunger is made of SK4 plated with nickel. Another plunger is made of brass plated with gold and nickel.

For details of SWP300 switch probes please check below parameters.
