Vehicle indicator lamp control circuit - has timer to intermittently energise relay supplied from constant voltage circuit

摘要

The control system is used for flashing indicator lamps of motor vehicle provided with rotating magnetic generator. The switching cycle of these lamps is held constant. The flashing cycles of front and rear lamps are also held constant. A relay (2) moving contact (3) is connected to the generator (1). It has at least one fixed contact (4a) which switches on the lamps (7, 10 or 8, 11) on one side of the vehicle at each end position of a double changeover switch (6). The winding (15) of the relay (2), which is intermittently energised by the timing device (14) is fed by the generator (1) through a rectifier (12) and stabiliser (13) with a constant voltage.
