<p>The invention relates to a delayed- action warning control circuit, in particular of a type intended to be connected in series with a warning device such as a warning light and a contact for detecting a threshold level of a liquid, such as a fuel. The control circuit has two terminals between which are connected a capacitor in series with a resistor. Control means monitor the voltage across the capacitor and short-circuit said terminals if the monitored voltage exceeds a predetermined value. <IMAGE></p> |
