Lights do not always need to be on at full power. Often it would be useful to be able to turn off the more powerful lights to achieve softer illumination, but this requires an installation with two separately-switch-able circuits, which is not always available.   Energy-Saving Switch Circuit Image  If the effort of chasing out channels and replastering for a complete new circuit is too much, then this circuit might help. Normal operation of the light switch gives gentle illumination (LA1). For more light, simply turn the switch off and then immediately (within 1 s) on again. The circuit returns to the gentle light set-ting when switched off for more than 3 s. There is no need to replace the light switch with a dual version: simply insert this circuit between switch and lamp. Energy-Saving Switch Circuit Diagram Parts List: Resistors: R1 = 100Ω R2 = 680Ω Capacitor: C1 = 4700µF 25 V Semiconductors: D1,D2 = 1N4001 Miscellaneous: K1,K2,K3 = 2-way PCB terminal block, lead pitch ...
