A method for galvanically isolated transmission of a signal, especially a switching signal for controlling at least one switching means includes using a transformer. The primary side of a transformer is fed with a pulse-width modulated voltage in which different duty factors are indicative of different signal states. The voltage obtained on the secondary side is converted by an electronic circuit into at least one signal voltage which is dependent on the duty factor and whose magnitude represents a signal state.
