摘要： A telephone stand has a housing with a cradle in its top for a handset adapted when placed in the cradle to depress a pair of laterally spaced plungers passing through holes in the housing down into its interior. A line switch is disposed in the housing below and laterally between the plungers. The plungers are coupled to the switch by a Y-shaped piston comprising a crosshead spanning the lateral spacing between the plungers, a pair of tines projecting upwards from laterally opposite ends of the crosshead and having vertical bores therein in which lower portions of the plungers are received, and a laterally central stem extending down from the crosshead and having camming surfaces thereon adapted upon downward displacement of the piston (by downward driving of either of both of the plungers) to wedgingly displace resilient blades in the switch to change switch conditions thereof. A spring passes up through a hollow in the stem to urge the piston upwards and impart to it a floating support which is stabilized by the plunger portions in the tine bores. The tines have upwardly and outwardly facing "L" shaped notches formed in their upper ends to prevent jamming of the downward displacement of the piston when only one of the plungers is driven down.

摘要： The invention is directed to a telephone structure that eliminates the need for fasteners to assemble a keypad and secure the keypad in place in the telephone. This is accomplished by a telephone that comprises a hollow housing (100) having a face portion (120) that includes an array of holes (122) and a keypad assembly (400) that comprises a sandwich of a static shield (430), button member (410), and switch contact member (450). The keypad assembly is assembled on the underside of the housing by means of a locating member (300) which has upstanding collar portions (325) that register in the holes of the face portion and depending pins (328) that register in holes in the members of the keypad assembly. The keypad assembly is held in place by a base member (200) that is joined to the housing and supports a raised pedestal (210) that extends into close proximity with the underside of the face portion and presses the keypad assembly against the face portion (FIG. 1).

摘要： A stand for a telephone set comprises an open-bottomed housing providing at its top a handset cradle to the rear of a housing upper wall slanting up towards the cradle and having a large aperture in it. A keypad has keys projecting outward within the aperture and, also, an upwardly slanting cover framed by the aperture. The keypad is secured to the housing by screws passing through support tabs at the side margins of the aperture and into the casing. A faceplate covers the heads of those screws. A printed wiring board with printed wire conductors and bulk telephone set components on, respectively, its upper and lower sides is secured beneath and to the keypad to be spaced from, and have the same upward slant as, the keypad. Mounted on the rear of the board is a line switch with a spring biased pivotable actuating lever. The outer end of that lever is coupled by a slidable bearing lost motion contact with the central part of an "H" shaped rocker member disposed above the lever and pivotable about an axis frontward of the lever's pivot axis. The rocker member has rearwardly extending arms bearing against the bottoms of plungers slidable in guide holes in the housing to project above the bottom of the cradle and be driven down into the housing when, respectively, a handset is not in and is in the cradle. The yieldable spring bias in the switch lever is transmitted via the rocker member to the plungers. The housing's bottom is closed by a base plate having no components mounted in or on it.
