Mount these sockets to fixtures, attach wire from your electrical testing equipment, and add Spring Test Probes to create automated systems to test continuity in circuit boards. Use a probe that has the same minimum spacing between probe centers and has the specified barrel length. Test probes and sockets are sold separately.

When installing test probes and sockets, adhere to the "minimum spacing between probe centers" to maximize testing points while preventing probes from interfering with each other.

Quick-Disconnect-Terminal Wire Connection—Sockets with a quick-disconnect terminal connection require an adapter (sold separately) to quickly and easily connect and disconnect your wire from the socket terminal. All of these sockets click in place for a hold that’s more secure than wraparound wire terminal connections, but less secure than solder connections. They also have sleeving for electrical insulation.

Jack—Sockets with a jack have a lower profile and offer a more secure hold than those with a plug. Use a crimper (not included) to install wire onto the adapter. These sockets can’t be reused due to their crimped connection.

Plug—Sockets with a plug offer the fastest wire installation time. Simply slide the plug over the wire and barbs will grip the wire sleeving—no need for crimpers. These sockets can be reused. They are not, however, as secure as those with a jack because their hold can loosen over time.

Wraparound Connection—For sockets with a wraparound wire terminal connection, install wire by winding it around the squared terminal on the socket. Their connection is not as secure as quick-disconnect terminal and solder connections. Add additional sheathing, such as heat-shrink tubing (not included), for electrical insulation.
