<p>PURPOSE:To automatically turn off an emergency lamp to surely preventing the emergency lamp from being left on, by turning on the emergency lamp along with the operation of a hazard switch and also detecting the action required for car driving and turning off the lamp thereby. CONSTITUTION:When the button 5A of a hazard switch 5 is depressed while a car is out of order, electric current flows from a power source 1 to the exciting coil 8 of a self-hold relay circuit 6 through a flasher circuit 3 and respective terminals 5B and 5C of a cancellation switch 11 and hazard switch 5. For this reason, even if the button 5A is released, the relay circuit 6 is made to hold itself for flickering respective lamps 2A and 2B through respective contact points 92 and 93. In starting the car after completion of repairs, when a direction indicator switch lever 12 is rotated clockwise R, the protrusion section 12A of the direction indicator 12 releases the cancellation switch 11 for stopping the current to flow to the relay circuit 6. As a result each of lamps 2A and 2B is automatically turned off.</p> |
