A low-voltage control circuit and method utilizing a single push-button switch or multiple push-button switches for controlling any of various high-voltage electric devices, and especially lamps. and a method to control said devices by a single push-button switch. The electronic push-button switch(es) operate(s) an electric device(s) by applying control signals to a microcomputer (10) due to different ways of pressing the switch(es). The microcomputer (10) controls a regulator (11, 14, 15) which controls the flow of current to the electrical devices. The switch is connected to the regulator and microcomputer via a pair of wires carrying low-voltage (e.g. 12 volt) signals. The actuation of the device(s), as well as the selection of mode of operation and the preset of time periods, is preferably done by a single switch, however, multiple switches can be connected in parallel to control a single device. |
