Abstract
A circuit (S1) for switching on an electrical load which can be connected downstream from the circuit comprises a first electronic switching means (T1) in a first path, and a second electronic switching means (T2) in a second path, which is in parallel with it. The circuit also has a means (INV, OR, T5) for producing the electrical control variable (Ugate2) for the second switching means (T2), which determines the control variable (Ugate2) as a function of an electrical variable (U0,d) which occurs on the output side of the first switching means (T1) when switching on a load which can be connected downstream.
