Switch Probes
The most common
use for Switch Probes
is in the cable harness
testing industry. The
Switch Probe is used
to verify the correct
location of a terminal
in a connector while
also checking the
retention force. In
addition, Switch
Probes also verify
the presence of
non conductive
components such
as caps for connectors
or devices on a circuit
board. There are two
separate current paths
in a Switch Probe.
From the plunger tip
to the tail is normally
open and closes only
after the probe
deflects to the
designated travel.
The second path,
from the plunger
tip to the outside of
the receptacle, is
always closed.
