hi people...
im just going to ask if is there some king of circuit that can cut a power line from a outlet?
and can you tell me guys how?

 

the simplest type is known as a circuit breaker. more info needed to give a morr specific answer. sensing current flow and operating a relay would be another.

 

A switch works wonders, but you have to stand by to opperate it when necessary.

Perhaps you should share some other facts about your needs.

 

Under what conditions do you want the power cut from the outlet?

 

Lamp timer?

 

it is suppose to cut automatically by timer...

 

Google, "outlet timer".

i know there is already a device for that...
im asking if how does it cut it off?
and im not talking about analog type...'
im thinking about the digital version...

 

a timer cuts off power with a switch. some are mechanical and just open a set of contacts. others use a control voltage to operate a solid state relay.

 

The ones I design usually fire a triac...or not, and "not" means, "off".
