This is a simple auto off circuit. The switch energizes the capacitor witch turns on the transistor. The 100k resistor drains the capacitor intern shutting down the transistor. On this circuit the transistor controls the relay.
I want to make emergency light circuit which light on by battery when power cut but when power come again it start charging the battery and switch off the light but it should auto cutoff the charging when battery get full charge can you share the circuit diagram ....
