Abstract

1295905 Uses of luminescence W PREH [trading as PREH ELEKTROFEINMECHANISCHE WERKE JAKOB PREH NACHFOLGER] 17 Feb 1970 [8 March 1969] 7637/70 Heading C4S [Also in Divisions E2 F4 H1 and H3] A channel selecting unit for HF receivers such as television sets with capacitive diode tuning has voltage dividers 1 provided with adjusting and indicating elements 2, 3, 4 for producing stored tuning voltages and switches 1, 2 are arranged in a row and are operable by keys 10, 13 which are mounted in a hinged flap door 7 for covering the adjusting and indieating elements. As shown in Fig. 2, the handle part 13 of the lever key 10 is pressed so as to slide in switch knob 2. A luminescent plastics pin 15 projects into a hole 16 in the pressed key 10 to show it has been pressed. Pressing another key 10 releases the previously pressed key. Blade spring tongues 14 press the keys into light engagement with the ends of the knobs 2 and when the flap door 7 is opened these blade springs engage a chamfered face (7<SP>1</SP>, Fig. 5, not shown) on the door 7 and hold it open.
