The invention relates to an energy supply circuit of electric components, in particular for a motor vehicle, having an accumulator, wherein a discharge monitoring circuit monitors the energy stored in the accumulator. If the energy stored in the accumulator falls below a threshold value, the discharge monitoring circuit switches off the energy supply at least of individual components, in particular of all components.

Energy supply circuit for electric components

The invention relates to an electronic lock for a locking system, in particular an electronic ignition lock for a motor vehicle. The lock has a holder into which an associated electronic key can be introduced. The key, which is in the holder, exchanges at least one coded operating signal with the lock. After positively evaluating the operating signal, the holder can be moved into at least one actuating position. The lock has a blocking element which adjusts on introduction of the key into the holder and/or removal of the key from the holder. Movement of the holder is possible when the key is correctly in the holder. Furthermore, the lock has a switching element on which the adjusting movement of the blocking element exerts a switching action via a separate transmitter which can be brought into operative connection both with the blocking element and with the switching element.
