The present invention is a switching element that is thermally responsive, switches between a state that is less permeable to radiant energy and a state that is more transmissive to radiant energy, and includes a liquid crystal medium, The switch element. The invention further relates to the use of the switch element for regulating the flow of radiant energy between the interior space and the environment and for regulating the temperature of the interior space. The invention further relates to a liquid crystal medium, characterized in that it contains from 5 to 60% of a compound of the formula (I), in particular the liquid crystal medium for use in the switch element of the invention. |
