Abstract
A jackfield with front removable jack modules having lamp assemblies. Each jack module includes a printed circuit board having a lamp assembly and a tri-jack extending forwardly therefrom. Conductor pads at the rear of the printed circuit board removably engage contact spring terminals interconnected to lateral busses. One bus provides a voltage and the other provides ground for the lamp assembly. One of the circuit leads is routed through the jack so that when a plug is inserted into the jack, the lamp is lit. The module also has wire wrap lugs extending from the rear, and the wire wraps are disconnected before the module is removed to the front. Apparatus is also provided for retaining the module from forward movement when only the tri-jack is to be removed.
