Abstract: A method and apparatus for monitoring the state or condition of charge of a battery which supplies a plurality of electrical consumption devices in an electronic circuit. A consumption device is operatively connected to a series of counters so that the count condition charges in response to a pulsing rhythmic cycle by one of a plurality of numerical values toward a final count condition, in which the numerical values are specific in relation to the power consumptions of a plurality of electrical consumption devices, and that a signal is generated upon the reaching of a final count condition.

Abstract: An electronic switch apparatus with a capacitor power supply portion which superimposes a current on a consumer circuit encompassing a plurality of power or current consumers which are individually actuatable by a control circuit; for example, consumers including a display module or subassembly, a relay and a control device. At least two of the power or current consumers are connected in series, wherein a switch branch line is connected in parallel with each of these current consumers, wherein the branch line is not conductive when a current flows through the switched-on current consumer which is connected in parallel therewith, which current is also adequate for the other current consumer, and wherein the branch line conducts a current which is adequate for the other current consumer when either no current flows through the power or current consumer connected in parallel therewith or a current flows therethrough which is itself is insufficient for the needs of the other current consumer.
