摘要

A first push-botton (10) forms a closing switch when actuated for a short period for a capacitor (22) charging current from the accomulator voltage (UA). The capacitor voltage, after at least partial charging, triggers the excitation of a relay (32) which controls a switch (34) for connection between the battery and a feed voltage terminal (34) of the circuit (36) of the electronic appts. It also closes a holding circuit (31,12,13) for the relay. A second switch (30) forms a circuit breaker whose actuation closes the capacitor discharge circuit to render the relay currentless and thus to break the relay controlled switch.
