PURPOSE:To improve the reliability of a turn signal indicator by separately controlling right and left turn signal lamps with first and second contacts through first and second relay coils excited by a latch circuit. CONSTITUTION:A coil of relays 6 and 8 is connected in series to a flasher 3 as a load. Right and left latch circuits 5 and 7 excite the relays 6 and 8 when reset with setting contacts 9 and 12, while the coil of the relays 6 and 8 fails to be excited when it is reset with resetting contacts 11-1 and 11-2 or handle turning direction detecting contacts 10 and 13. This reduces the number of relay contacts controlling large current to two as compared with the conventional type thereby improving the reliability. |
