Electrical sensor circuit

摘要

An electrical sensor circuit which reacts to a defined physical change, which occurs within a predetermined region, by changing the operating state of an electrical load apparatus, to be precise in that the small current flowing through the sensor is used directly or indirectly for disconnection. This sensor circuit can be applied, for example, in the case of apparatuses which can lead to a hazard in the event of contact with water (for example hairdryers or fan heaters in the bath tub) or in the event of overtemperature (for example irons or hairdryers).
