  • Patent number: 6020659
    Abstract: The present invention relates to an electronic switch system for controlling AC power to a load. The switch has ON, OFF and RAMP down modes that can be selected by means of momentary touch switches. When put into the RAMP down mode, the power to the load decreases slowly at a gradual continuous uninterrupted predetermined rate. This switch system has particular utility in brightness control of lamps. It has been found that the use of a lamp controlled by an electronic switch of the present invention often will induce sleep for people that have difficulty going to sleep, particularly young children and older persons. Thus the electronic switch system and devices embodying this system are particularly useful in a method to induce sleep.
