In a switching arrangement for controlling a load-controlled power switch via a transformer Ü, a voltage signal is inputted into the transformer, the voltage signal being comprised of impulses of short duration T1p, T1n in positive and negative directions. Two field effect transistors F1, F2 at the secondary side of the transformer Ü convert the impulses T1p, T1n into impulses T3p, T3n in positive and negative directions which reliably control the power switch LT, the impulse duration of the impulses T3p, T3n being extended to the beginning of the next input impulses with reversed voltage directions T1n, T1p. A diode D1 and D2, respectively, is disposed in each of the field effect transistors F1and F2 between the source terminal S and the drain terminal D thereof. A respective series switch is activated ahead of the gate terminals of each respective field effect transistor F1 and F2.
