Switch Probe Pogo Pin SWP298 Series for Electronic Test

Switch Probe Pogo Pin SWP298 Series for Electronic Test

Switch 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 switch probe we will introduce is SWP298. Its diameter is 2.98 mm and total
length is 49 mm.

As usual, switch probes do not entail very high currents, and this model SWP298 can
work with the current up to 3 A.
The typical maximum contact resistance of this model SWP298 is 50 mΩ.

The materials used for the construction of switch probes are different for each
component:
The barrel is made of brass. Subsequently gold and nickel plated during the
galvanic plating phase.
The spring is made of SUS.
One plunger is made of BeCu plated with gold and nickel. Another plunger is made of
brass plated with nickel.
The insulating sleeve is made of POM

For details of SWP298 switch probe, please check below parameters.
