DEVICE FOR AUTOMATIC CONTROL OF POWER TO AN ELECTRICAL LOAD AND CIRCUITS THEREFOR

摘要

A device for producing a gradual change in power supplied to a load or plurality of loads which utilizes at least one gated solid state switching device (15). Dimmer switches are well known in the art but these switches are manually operated and the human eye requires approximately 15 minutes to fully adjust from a dark environment to a normal, well-lighted environment, or light to dark. Such problems are solved by the use of a timer select switch (SA) for producing a gradual increase or decrease of the light source (20) such that the human eye has ample time to adjust to the surrounding light conditions.
