Abstract
Connection network part for television apparatus with a protective circuit 25 against overloading on the primary side and a regulating circuit on the secondary side and a starting circuit 24 with final disconnection of the network component. In the event of interruptions on the primary side, the protective circuit causes a negative voltage spike on the secondary side. This is compared in a comparator 32 with a secondary voltage (standby) produced independently of the connection network part, which comparator supplies a control voltage to which the protective circuit on the secondary side reacts and which switches off the activation of the change-over switch in the network part. <IMAGE>
