Abstract

807,286. Keyboard switches. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 10, 1956 [Aug. 13, 1955], No. 24557/56. Class 38 (5). A push-button switching device for wavelength changing in radio receivers has the movable contacts 17, 19 mounted on respective carriers 13, 15 on slidable strip members 9, 11 provided with cam surfaces with which the tapering ends of the press-buttons 3 engage. As shown, depression of the second button has moved slide 9 to its right-hand position and slide 11 to the left-hand position. Fig. 2 (not shown) illustrates diagrammatically an arrangement having seven buttons and two slides.
