<p>PURPOSE:To prevent bad effects of sparks produced at contacts by connecting transistors in series with direction indicating devices and connecting a synthesis of an intermitting signal of a lever switch and an automatic intermitting signal to the base circuit of the transistors. CONSTITUTION:Transistors 4, 15 are provided for synthesizing a signal of a lever switch 7 and an intermitting signal from an automatic intermitting device 2. If contacts 9, 11 of a lever switch 7 are connected with each other for turning left, a direction lamp 12 starts automatic flickering. If contacts 9, 8 are connected with each other, a direction lamp 6 starts automatic flickering. If the contact 9 is not connected with either of them, neither of the direction lamps 6, 12 flickers. Which this constitution, current for a control circuit can be set low by combining highly sensitive transistors with it, thereby had effects of sparks at contacts can be eliminated.</p> |
