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.

Drill Size: #41

Mounting Hole Size: .094/.096 (2.39/2.44)

The size 3 switch probe shown does not require

a receptacle. The barrel of the switch probe

is designed to mount directly in the mounting

plate.
