Abstract
A warning display system provides a warning when it detects an abnormal condition in an operating element closely related to the safe operation of a vehicle. An abnormal condition of an operating element is detected by one of a plurality of sensors each provided at a corresponding operating element. Detected signals of the sensors are fed as input to the fixed contacts of a rotary switch. The sliding arm of the rotary switch and a rotary drum are connected to a rotary driving device. The rotary driving device is driven step by step by the output of an energization circuit which generates a pulse signal. The drum has a plurality of display items indicated on its circumference, which display items respectively correspond to each fixed contact of the rotary switch. A display window is provided adjacent the drum for visual observation of one of the display items at a time. A control circuit discontinues the operation of the energization circuit when the sliding arm of the rotary switch reaches the position of the fixed contact corresponding to the sensor which detects an abnormal condition.
