Anyone know how to make this? For example if i press the button, the other one will ring. Anyone tell me how to do it?

 

Wired? Wireless? Distance?

You mean like a two way door bell setup? The circuit below will work as long as SW1 and SW2 are not pushed at the same time:

Pushing both SW1 and SW2 will short circuit the batteries.

So just dont push them both at the same time

 

Wouldn't a low voltage AC source on one side work with a little modification?

Why not just use three wires?

Standard mains cable is cheap enough.

I'd thought of that but wanted to keep it as simple as possible until we get some feedback as to what the OP really wants.

Wireless. Distance about 50 meters will do.
