Abstract
The invention is directed to an electric circuit arrangement (,) for checking a series circuit including a switch (,) and a load (,). The circuit arrangement (,) includes a first circuit (,) which is connected to the connecting circuit node (,) between the switch (,) and the load (,) and is suitable for detecting a first state. The first state defines a short circuit of the connecting circuit node (,) to the supply voltage (,). Furthermore, a second circuit (,) is connected in parallel with the first circuit (,) and is connected to the connecting circuit node (,). The second circuit (,) is suitable for detecting a second or a third state. The second state defines a short circuit of the connecting circuit node (,) to ground (,) and the third state defines an interruption of the connecting circuit node (,) to the supply voltage (,).
