Switch Probe Test Pogo Pin SWP137 Series for Connection

Switching Probes is 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 switching probe we will introduce is SWP137. Its diameter is 1.37 mm and total length is 30.75 mm. 

As usual, switching probes do not entail very high currents, and this model SWP137 can work with the current up to 3 A. 
The typical maximum contact resistance of this model SWP137 is 80 mΩ.

The materials used for the construction of switching 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 and nickel plated.
The insulating sleeve is made of POM
