ABSTRACT:
A master structure supports a plurality of independent switching and control units. Insertion of a switching and control unit into the master structure makes electrical connection. Load carrying circuits are automatically bridged by the removal of a unit. A test connector and plug enable in-circuit isolation and test of the electrical components within a unit. Mechanical keying insures correct location of units within the master structure.
