Abstract: The fastening of a circuit board in a housing that has a front faceplate panel with actuating means thereon for activating switches that are mounted on the circuit board is effected by a self-compensating latch apparatus. The apparatus employs a plurality of mounting ledges molded to the side walls of the housing and spaced a chosen distance from the font panel upon which the circuit board rests. A plurality of resilient fingers with locking devices attached to each finger are integrally molded within the walls of the housing near the mounting ledges. The fingers flex away from the edges of the circuit board as the board is introduced into the housing via a rear opening. Then the fingers flex inwardly causing arch-shaped members of the locking devices to move over the rear edge of the circuit board to a location whereat the front of the circuit board is locked against the ledges. By use of this invention, circuit boards of varying thicknesses can be locked into such a housing.

Abstract: A unique system for packing and distributing electrical signals within an electrical machine is disclosed. Electrical distributing circuit conductors are pre-printed or pre-plated directly onto the inside surface of the machine covers. A pluggable edge connector is provided for interfacing the plated electrical conductors with pluggable electrical devices or electrical cards. The connector is fitted with independently switchable contacts which allow a pluggable electrical device or card to be electrically coupled with a respective pre-plated/pre-printed conductor or a discrete wire conductor. As a result, changes in the distributing system can be made without changing the plated lands pattern on the machine covers.
