what kind of switch can break the circuit if an electrical signal came into the switch ?

Question

I am looking for some sort of "electronic switch" rather than mechanical switch .... so I do not have to break the circuit by moving the switch button , instead only a small electrical signal enter to the switch (through some wire) can cause the switch to break the circuit ....
is there a switch that can break the circuit at some current (this is present so far BUT ALSO : ) AND return back when the currency change by itself ???

A relay would work, but it is not electronic, it is mechanical or more precisely - electro-mechanical.

Instead, you need to use a MOSFET to do the job. The particular device is called a Load Switch. One example of this device is the Fairchild FDC6330L. Small gate control current, reasonable Ron, etc. Have used them for years. There are others as well.

turn off circuit breaker to this area. examine to verify capacity is off. do away with wires from from swap discover out which wires bypass to outlet, and which wires bypass to gentle. turn circuit breaker on and notice which cord is warm turn breaker off connect warm cord to a minimum of one terminal of the swap, and to the cord going to the merchants. connect cord to the gentle to the different terminal on the swap The (WHITE) independent wires could be all linked at the same time.

You need a relay.

And an education in electronics so that you know how it works.
