Abstract (en)
[origin: DE102005061532A1] The circuit has a switch (3), which comprises a main contact (4) and an auxiliary contact (5), arranged in parallel with the semiconductor switching element (2). The main contact and the auxiliary contact are coupled in such a way that the switching state of the auxiliary contact changes before closing and after opening of the main contact. A controller (6) is provided, which switches the semiconductor switching element on as a function of the switching state of the auxiliary contact before the main contact closes and switches it off after the main contact opens.
