Abstract

In a method of supervising the state of an electrical contact (11) present in a load circuit (12), an output signal is generated by a detection means (4) present in a supervision circuit (1) also connected to said contact (11). The output signal changes depending on whether the contact (11) is open or closed. Thus, the state of the electrical contact (11) can be monitored. <IMAGE>
