Abstract
An electrical contact test probe for use in providing electrical continuity between diagnostic equipment and a test point of an electrical circuit under test is provided. The test probe includes an elongated plunger slidably mounted within an elongated tubular barrel and extending outwardly therefrom for contacting the test point of the circuit under test. A spring is seated in the barrel and is interposed between the barrel and the plunger for biasing the plunger axially and outwardly of the barrel. The barrel consists of an elongated body having an inner bore, a generally closed end, and an open end. The barrel also has at least one cantilevered tab struck from the body and having a free end projecting into the inner bore toward the generally closed end of the barrel. The tab is located on the barrel such that the free end engages a shoulder of the plunger when the plunger is in an extended position so as to prevent outward biasing of the plunger beyond the extended position. The tab thereby retains the plunger within the barrel during the testing of the circuit.
