Day Night Switch

You shouldn't have more than a 10A breaker unless you are running high wattage lights. You should not have more than half your house lights on a single breaker. A good electrician will balance the outlets and lights depending on their usage. i.e half the bedrooms and half the living area on each breaker. That way you are not putting too much through each breaker. Outlets should be on 3 or more breakers. High draw areas, like the kitchen, should not share with the laundry. Also you wouldn't have your whole kitchen outlets on one breaker.

Ya you correct typically lights should be 10A either way still need a crap load of wattage on lights to get that high amps

I have a 10W LED spot light on my desk. It is rated 50mA. So 200W to 1 amp.

yep that's pretty much correct (or to be more closer accurate 0.9 at 220V and 0.8 at 240V)
Any way below what the switch or circuit breaker can handle

I'd love to know how that works

Schmitt Trigger Circuit Using Op Amp – Example 1

This Schmitt trigger circuit uses a 741 compatible operational amplifier (op amp) to convert a slowly changing input waveform into one with with sharp transitions.

On this circuit, I replace R2 with an LDR.

How an LDR (Light Dependent Resistor) Works

A light dependant resistor or LDR is a sensor that changes resistance as the light level changes, see example circuits and explanations in this tutorial. This tutorial also covers what an LDR looks like, the circuit symbol, typical resistances for different light levels and some example...

for the power supply I use a old charger any any relay with the correct amp settings.
I did this because my switch must fit inside this
