Telephone line switch
-
Hi everyone.
I'm looking for a way to switch on/off my telephone line. As we have a litte baby we dont like to be desturbed after 8 PM. i thought about a swith in the telephone line. any ideas?

@stingone I think it could be achieved by a relay. I know from the guy from hackaweek at youTube, that there can be peaks of up to 50V on a telephone line. I don't know the amperage, but you can measure that.

Normaly its arround 40V DC between A and B
When being called 40V DC + 20 AC 25Hz.
When the line is open it drops to 10V DCAmps is arround 30mA
Dont know what kind of relay to use to achieving this.

The relay example should work fine I think.
