<p>PROBLEM TO BE SOLVED: A pair of lamps are both flashed in a predetermined time interval by incorporating a control circuit part and a lamp open and close relay in a hazard switch. SOLUTION: A control circuit part 1 and a lamp open and close relay 2 are incorporated in a hazard switch 5. When the hazard switch 5 is operated, a turn terminal 22a and a pair of lamps 41 and 42 are both connected so that a contact point 22 of the lamp open and close relay 2 are closed with a pulse voltage of the oscillation circuit 11 in this state. When the circuit is closed, the turn terminal 22a is directly connected with a battery 13 via the control circuit part 1 so that the pair of lamps 41 and 42 are flashed at a predetermined time interval.</p> |
