ABSTRACT:
Network interface device in the form of a switch comprises a dielectric base with a cover slidably mounted thereon. Parallel first and second spade terminals upstanding from said base alternate in a first row. The first terminals are part of contacts connected to subscriber's wiring, the second terminals are part of contacts connected to network wiring. Parallel third and fourth spade terminals upstanding from said base alternate in a second parallel row. The third terminals are integral with contacts having second terminals thereon, and the fourth terminals are part of contacts connected to spring contacts in a test jack. Four pairs of first and second terminals lie directly opposite four pairs of respective third and fourth terminals. Bridging contacts in a third parallel row on the cover connect first and second terminals when the cover is closed, connecting the network to the subscriber's wiring. When the cover is open, the bridging contacts connect third and fourth contacts, the test jack is exposed, and the network wiring is connected thereto while the subscriber's wiring is disconnected.
