Abstract: An electrical jack is disclosed having an elongated nonconductive housing with a cylindrical opening for receiving a plug having tip, ring, and sleeve members. Corresponding tip, ring, and sleeve spring assemblies are positioned in the housing generally transverse to the cylindrical opening for engagement with the plug members and each assembly has a pair of break contacts which are opened to interrupt circuitry connected thereto, when the plug is fully inserted into the jack opening. The ring spring assembly is further arranged to engage the tip of the plug when the plug is partially inserted. The ring spring assembly positions the plug so that the tip and ring of the plug engage the ring and sleeve spring assemblies of the jack without opening the break contacts. Partial insertion of the plug permits bridging onto the circuit connected to the jack without interrupting the continuity of the circuitry connected through the break contacts.
