Abstract: A circuit card interface system of minimized vertical clearance, capable of interfacing one or more circuit cards to a relatively small space on a mother board. The interface system includes an interfacing connector assembly and at least one stacking connector assembly, each adapted to receive a circuit card. The conductors of the interfacing connector assembly are coupled to a substrate such as a mother board. The interfacing connector assembly can be used alone or with one or more electrically interconnected stacking connector assemblies. Rapid electrical attachment of each stacking connector assembly is accomplished by mating a cooperating portion of the stacking connector assembly with a portion of the underlying interfacing connector assembly.

Abstract: A method for constructing a multiple-pole switch of the dual in-line package type initially manufacturing a base unit with integral terminals and a cavity for each pole. A movable contact having first and second end portions and intermediate portions are deposited in each cavity. A double-injection molding process produces a rotatable actuator and a cover that is assembled onto the base unit to capture the movable contacts in their corresponding cavities.
