Abstract

1464666 Direction-indicator flashers SWFSPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU GmbH 17 Feb 1975 [25 May 1974] 6570/75 Heading G4Q [Also in Division H3] Relates to a direction-indicating flashing circuit which incorporates a relaxation oscillator utilizing transistor T1 and a switching circuit utilizing transistor T2, the flashing of lights connected to terminal 49a being effected by contact s of relay S and the frequency of flashing being determined by capacitor C2. According to the invention a filter capacitor C1 is connected as shown. An analogous circuit utilizing NPN transistors may be utilized. The purpose of the invention is to prevent "fluttering" caused by oscillation at the beginning of the pulsing and interval times.
