摘要

Bi-stable circuit arrangement for monitoring a predefined filling level range in a filling pipe comprises a floating switching magnet that rises or falls with the filling level causes a bi-stable switch to be activated. the switch arrangement comprises two switch elements (S1, S2), each serially connected to a CMOS gate (G1, G2). The CMOS gates are connected to a storage flip-flop (10).
