ABSTRACT:
An improved telephone circuit module incorporating a bridge lifter switching means which permits direct connection of party line subscriber circuits to a terminal block with the elimination of prior art saturable bridge lifters normally mounted upon a main distributing frame, and accompanying cable runs. The bridge lifter module comprises a solid state thick film circuit formed upon a ceramic substrate, suitably encapsulated, and is sufficiently small in overall size to fit within a connecting module which engages a part of a housing, and electrically conductive wire wrap terminals of certain types of known connector blocks.
