Abstract

844,523. Radio receiving-sets. LOEWE OPTA A.G. Dec. 24, 1956 [Dec. 23, 1955], No. 39174/56. Class 40(5). A radio or television receiver having push button control of wave band and of tone colour has the positions of the tone colour push buttons indicated by optical means separate from the push button assembly. As shown, a partition 9 moulded or die cast from plastic material contains windows 10 which are illuminated by one or more lamps when the appropriate tone colour push button 8 is depressed. The windows may alternatively be illuminated by flood lighting or by light directed on them by glass rods or plates. A further range of push buttons 7 controls wave band and on-off switching. Manual controls 16, 18 for high and low note response may be switched in by push buttons 15, 17 respectively.
