Abstract
A measuring arrangement includes a first magnetic switch having a first contact and a second contact, and a second magnetic switch having a first contact and a second contact. A first evaluation terminal is connected to the first contact of each of the first magnetic switch and the second magnetic switch. A first resistor is arranged between the second contact of the first magnetic switch and the second contact of the second magnetic switch. A second evaluation terminal is connected to the second contact of the first magnetic switch. A third evaluation terminal connected to the second contact of the second magnetic switch.
