<p>The indicator is used in the motor-car industry. It is included in the electrical circuit of the stop-lights without breaking the factory-made integrity and indicates any faults of the stop-light lamps as a new function of the factory-assembled indicator lamp for low-level braking fluid. The indicator consists of a current sensor (2) which, when the braking pedal (9) is pressed down, by means of the first capacitor (C1) it becomes connected in parallel to the electric circuit supplying the stop lights (7), and in case of a released pedal being connected in series in the circuitry of the stop lights (7) by a control device (3) and an indicator - a lighting lamp (4). In case of a released pedal and a fault in the stop-lamps, lamp (4) lights up as a result of the earthing of the lead (9) by a signal generated by the control unit (3). After sometime, determined by the RC-circuit (R5-C2) of the control unit, lamp (4) switches off as a result of disconnection of the lead (g) from the frame by a signal generated from the control unit (3). 6 claims, 2 figures</p> |
