    • The invention relates to a control device for switching an electric consumer, especially an inductive consumer such as a three-phase induction motor. The inventive device has a control circuit (2, 3, 4, 5) providing the consumer (1) with a switchable supply of voltage and/or electricity, a device (8, 9) for detecting induced voltages arising from time-based modifications of the switched current dI/dt and a feedback circuit (6, 7) for controlling the feedback from the control circuit (2, 3, 4, 5) on the basis of an induced voltage thus detected, whereby time-based modifications of the switched current dI/dt are limited to a specific maximum value. This enables the rate of current rise or fall to be limited to an adjustable value without affecting the rate of change dU/dt of the voltage that is applied to the consumer (1) during the switching process.
