Abstract
Bei einem Druckschalter zur Überwachung des Drucks im Reifen eines Kraftfahrzeugrades ist in der Referenz druckkammer des Schalters zusätzlich zu zwei Kontakt elementen ein elektrischer Temperaturfühler zur Über wachung der Reifentemperatur angeordnet, wobei der Temperaturfühler ein temperaturempfindlicher elektrischer Halbleiter-Schalter sein kann, der zwischen dem einen Kontaktelement und dessen Anschlußleitung in Reige ge schaltet ist. With a pressure switch to monitor the pressure in the Tire of a motor vehicle wheel is in the reference pressure chamber of the switch in addition to two contacts elements an electrical temperature sensor for over Tire temperature monitoring arranged, the Temperature sensor a temperature sensitive electrical Semiconductor switch can be between one Contact element and its connecting line in Reige ge is switched.
