  • the invention relates to a window heater, in particular for heating a window of a motor vehicle, with those mentioned in the preamble of claim 1 Features.
  • Disc heaters of the generic type are known. These usually have a resistance heater, that of in the form of meandering arranged over the electric disc to be heated Ladders is formed.
  • the electrical conductors are thin, flat or linear Conductor tracks applied to a surface of the pane or - in the case of composite panes - in a space between panes integrated.
  • an electrical one Use switching means by an operator of the motor vehicle can be activated.
  • electrical Switching means for example, relays are used. These are usually on one in the dashboard of the motor vehicle arranged circuit board arranged.
  • mechanical Relay semiconductor switching means for example Power transistors to use, but for Adaptation to existing contact structures of the mechanical Relays are placed in adapter housings. In addition to the associated additional costs through the use of the adapter housing is the assembly on one, below a dashboard of the motor vehicle arranged circuit board relatively expensive.
  • the window heater according to the invention with the in the claim 1 features in contrast offers the Advantage that in a simple and inexpensive manner contacting the resistance heating device with a heating voltage source is possible.
  • the switching means one directly on the one to be heated Disc-arranged semiconductor switching means is is advantageously possible as standard components available semiconductor switching means without Interposition of an adapter housing directly with the resistance heater on the one to be heated Contact disk.
  • the disc to be heated at the same time serves as a carrier of the semiconductor switching means and thus in a simple manner through appropriate design the resistance heater a circuit board for Connection of the semiconductor switching means is simulated.
