Thermoelectric flectional switch for regulating heating systems has a bimetallic element at pretension pressure to snap on at snap temperature and to couple to a piezo element for moving the bimetallic element into contact.

摘要

A heating system has a thermosensor (7) and a heater (9). As a piezo element (3) bends in, a transmitter (8) is fed with electrical energy and transmits a radio sequence onto it via a transmitting antenna (12). This radio sequence can contain an ID code to make a positive identification of a thermoelectric flectional switch (1)/thermosensor (7). Independent claims are also included for a set of multiple thermoelectric flectional switches, for a thermosensor with a thermoelectric switch and for a method for operating a thermosensor.
