Abstract

The temperature controlled switching device has a bimetallic actuator disc Ä29Ü that is supported above a metal spring diaphragm Ä22Ü within an insulator insert Ü16Ü in a metal housing Ä13Ü. At the centre of the disc is a movable contract Ä34Ü that normally engages a fixed contact Ä24Ü on a cover plate Ä14Ü. The contacts are coupled to input and output wires Ä41,43Ü and a temperature increase is produced to cause switching at a specific point. An additional input is provided by a resistance heating elements on base substrate Ä26Ü that provides rapid switching for a sudden overload
