Abstract

PURPOSE: To warn an alarm by an automotive warning device in response to the degree of emergency by connecting a malfunction detection switch as the control switch of free-running multivibrator to allow a common alarm lamp to flash in response to the oscillation frequency of the multivibrator.
CONSTITUTION: Since a sensor switch 1a is closed as a malfunction detection switch if a malfunction occurs at a frictional pad, an alarm lamp 3 is slowly turned on. If an insufficient brake oil occurs as higher dangerous malfunction in a brake system, a sensor switch 1d is turned on to allow a free-running multivibrator 2d to be operated. The multivibrator 2d has the highest oscillation frequency to permit the lamp 3 to rapidly flash repeatedly. The lamp 3 repeatedly flashes in response to the characteristics of the multivibrators 2b to 2d. Accordingly, it can warn the alarm in response to the degree of emergency, of the malfunction.
