There''s a DC 6V adaptor powering load (resistor+LED) when mains AC power is available at home. 1K 10K resistor network biased to PNP transistor holds it in cut-OFF state when line power is available and thus disconnects the battery. But if there''s a power cut which is indicated by opening the spst switch placed next to 6V adaptor source, the ...
Automatically switch between household power and inverter when power …
What I didn''t realize is that the inverter is only for providing constant power, but does not switch between power sources. The inverter has a standard AC outlet on it for plugging in a load. What I think I''m looking for is a relay that switches between two 120 V power sources and sends the power to a single load.
