A regulating arrangement comprises a control signal input bridge having a transistor amplifier connected as a diagonal and an electronic switching device connected in series in the bridge output. Means are operable to vary rhythmically the value of one arm of the bridge, and the resulting bridge diagonal voltage is applied, as a control voltage, to an active element of the bridge controlling the bridge output. One arm of the bridge includes a negative temperature coefficient resistance and the other arm of the bridge includes a resistance whose value is varied rhythmically either by operation of a circuit interrupter or by an electric pulse transmitter.
