If such a signal arrives, it means that the transmitted control signal is not intended for this ripple control receiver and the command relay KR therefore does not have a switching

In order to prevent the blocking transistor T3 with its park-controlled charging of the pulse circuit behind the allele resistance RT to the respective other transistor diode D 1, the charges that arise in the circuit arrangement in question are connected via the between the pulse line, ie, the connection of the blocking transistor 3 and the discharge resistor connected to the negative pole must be laid from the connection point χ after the connection position R 13 to the negative pole 5 »point y . There is also the possibility, by connecting additional circuit arrangements, how the number of possible switching preselection pulse combinations suitable for the combination selection can be built up with the circuit arrangement described. According to a further embodiment of the described circuit arrangements 1 and 2 of this circuit arrangement, the blocking transistor φ3 can be used as a switching element in combination, as shown in FIG. 2, the common connection line of the work coils is connected to the connection point χ.
