Abstract
The invention provides a thermal switch, including a frame made of electrically insulating material, defining the perimeter of a cell fillable with liquid crystal (LC); first and second plate-shaped electrodes, each having an inside surface and an outside surface and being attached along the periphery of the inside surface on opposite sides of the frame, defining surfaces of the cell; first and second covers made of electrically insulating material, each attached to the outside surface of one electrode, the inside surface of at least a portion of each of the electrodes being treated to obtain anchoring of the orientation of LC molecules in a direction parallel to the plane of the electrode, resulting in improved performance of the switch.
