Abstract
A system for preventing frost from accumulating on a window of a motor vehicle has a heating element provided on the window, a temperature switch, which is closed when the temperature of window is lower than 0° C., and a humidity switch, which is closed when the humidity of air outside of the window becomes slightly lower than 100% relative humidity. When both the switches are closed, an electric circuit is closed to connect a battery with the heating element, thereby preventing the formation of frost on the window.
