Abstract: TELEPHONE HANDSET CHASSIS \A FLEXIBLE PRINTED CIRCUIT For a telephone handset; a rigid chassis is provided, of elongate form with positions at each end for mounting respectively a receiver and a transmitter and an intermediate position for a pushbutton dial. A flexible circuit member carries the majority of the various components for the handset. The flexible circuit is elongated and extends along the back of the chassis, down through a slot and back along the front of the chassis, with the pushbutton dial assembly attached to the flexible circuit member. The majority of the items such as electronic components, recall button, line cord jack and other components can be preassembled to the flexible circuit member which is then assembled to the chassis, followed by attachment of the pushbutton dial assembly.

Abstract: MODULAR SWITCH A modulator switch, such as can be used for telecommunication purposes has a hollow body within which are a plurality of cantilever contact members, there being a center contact member and at least one side contact member. The center contact is biased towards one side or the other and has an extension actuated by an actuator rotatably mounted on the body. Actuation to make, break or transfer contact can be provided. The switch can be designed for sliding on a cover or another switch. The particular selection of two, or three contacts provides the particular actuation required.

Abstract: BASE FOR TELEPHONE SET, FOR ALTERNATIVE DESK AND WALL MOUNTING An adaptable telephone baseplate can be used for either wall mounting or desk or table top mounting. The baseplate has an enclosed recess at an intermediate position and a modular jack position at what would be the top edge when wall mounted. A slot connects the jack position and enclosed recess. When wall mounted a short cord can be inserted in the slot with a plug at one end being inserted in the jack at the jack position and a plug at the other end being in the recess for insertion into a wall jack. When desk mounted a normal line cord enters through a groove into the jack position for insertion of a plug into a jack. Alternatively a line cord can enter through the groove, extend along the slot and then pass up through the slot for hard wiring of the conductors to a circuitboard. Snap-in mountings are provided for the jack, a circuit board, ringer and possibly other items. For some telephones a battery housing can be provided while in others the battery housing can be omitted, by the alternative use of two inserts in the mold for the baseplate.

Abstract: MULTIPLE CANTILEVER SPRING CONTACT HOOK SWITCH A multiple cantilever spring contact switch has a plurality of cantilever spring contacts, in one or more series, with the contacts of each series clamped between surfaces which provided a predetermined relative inclination of the contacts. A pivotal member is mounted on the switch assembly or actuation by an operating member, the pivotal member in turn actuating the contacts. The contact between operating member and pivotal member is localized so that misalignment between operating member and the switch assembly does not affect actuation ; of the contacts. Such misalignment can occur when the switch assembly or operating member or both are mounted on printed circuit boards. The switch is particularly suitable for a hook switch of a telephone.

Abstract: TELEPHONE SET BASE FOR BOTH WALL AND DESK MOUNTING A telephone set base, for both wall and desk top mounting, has an elongate plastic molded base plate and a top housing. To improve stability a flat metal weight is positioned on the base plate and is spaced a small distance from the base plate to form an acoustic chamber. A speaker is mounted on the weight. A printed circuit board is mounted over the weight and modular jacks are attached to a flexible circuit member which connects to the printed circuit board, speaker, and other items. Recesses are formed in the base plate to provide for alternative arrangements of line cords and plug-in mounting on a wall. Slots in the base plate provide access to the recesses for cords entering at the ends of the base plate. A battery housing is provided.

Abstract: MODULAR TELEPHONE CONNECTOR A modular telephone connector for use in providing connection of a telephone to both telephone lines and a separate power source, has a bottom member for fastening to a wall or other member at a required telephone position and a top assembly which attaches to the bottom member with a flat cable gripped between. On attachment of the top assembly to the bottom member, insulation piercing terminals pierce the cable and make contact with conductors in the cable. The top assembly includes a circuit board having conductor patterns to which the insulation piercing terminals are connected, and also to which are connected terminals from a modular jack, or jacks, mounted in the top assembly. A cover clips over top assembly and bottom member.
