Abstract: A switching arrangement for remote-controlled electrical loads employing command transmitters, each of which is operatively connected to a switching device for control of a load over cooperable coder and decoders which are connected by electric lines, with the coded signal being supplied over a transmission channel to the decoder which converts the coded signal into a switching signal, operative to actuate the switching device with the construction being such that standardizable components and connection lines may be utilized in the system.

Abstract: A novel circuit arrangement is provided for gating out pulses and/or pulse gaps whose duration is shorter than a given test period t.sub.p from a sequence of digital pulses present at the input end. The arrangement is such that the test period can be set with arbitrary accuracy and yet at the same time can be arbitrarily varied. It is insensitive to temperature fluctuations within wide limits.A principal feature of the present invention is to provide a circuit arrangement in which at least one counter is provided which may be set and which exhibits a setting input for the setting of a fixed or variable initial value in the counter, and in which the test period t.sub.p may be determined as a counter period from the initial value after a give value in the counter.
