Patent AT-E401662-T1: [Translated] CONTROL UNIT WITH THERMAL PROTECTION AND AN ELECTRIC HEATING DEVICE COMPRISING THE CONTROL UNIT

In its normal position fixed opposite a printed circuit board (PCB) (1), a contact breaker (CB) (3) forms an electrical interconnection between opposing ends on a strip conductor. Activated by overheating in a transistor (2), an operating element (4) acts against the CB when activated and detaches the CB so far from the PCB that an electrical connection is interrupted. Independent claims are also included for the following: (A) A pre-assembled operating unit for a contact breaker in an electromechanical overheating protection device; (B) and for an electric heating device with a layered casing, a radiator element, a metal contact sheet and an exothermic element.
