Abstract
PURPOSE: To permit the room lamps of a motor-vehicle to be turned on or off at hand by arranging the room lamp-controlling unit near the driver's seat.
CONSTITUTION: When a switch 3 is turned on, a switching IC5 for a motor-vehicle actuates an output transistor 8 to turn on, and consequently a room lamp 9 near the ceiling of the vehicle lights up and continues to light even if the switch 3 is turned off. When the switch 3 is turned on next, the lamp 9 is turned off by the similar operation. Moreover, when a door switch 4 is turned on, the IC5 actuates the output transistor 8 to turn on, consequently the room lamp 9 lights up; and when the door switch 4 is turned off, the IC5 turns off after the time set by the time-constants of a resistor 7 and capacitor 6 connected to the IC5 has passed. Therefore, the transistor 8 also turns off and consequently the lamp 9 turns off. Thus, the system operates as a time-lag light-putting out means.
