ABSTRACT:
A switch controller for providing on/off timing control of lights including a base unit, an electronic unit, and a cover unit. The electronic unit includes two printed circuit boards, one of which includes an integrated circuit controller for controlling an LCD display and for permitting input of timing information via buttons associated with the LCD display, and the other of which supports a relay, neon lamp, and transistors. The relay includes a pair of reed contacts for connecting a light to a power supply in response to the timing information. The neon lamp is dimmed whenever the switch is in an off status in order to provide a guide to enable location of the switch controller in the dark.
