The circuit has at least 2 semiconductor switches (15, 16) in series with the switched load (10). The detected voltage across the load is compared with a threshold value to provide a signal (35) when the load is switched in, compared with at least one load switching signal (30, 33) via a comparator (28) within the control stage (21) for the semiconductor switches. Pref. the comparator is supplied with an external switching signal and switching signals for the semiconductor switches provided by a selection circuit (29), together with a status signal (33) for the load. |
