When I worked for this huge corporation at the desktop publisher desk, we used to have this guy who would come in, layout his lunch and use our courtesy phone to conduct business from.

Needless to say, this wasn’t right.

We kept asking him to leave, and he just kept coming back.

Eventually I got tired of it, and decided to do something about it.

Enter, the phone kill switch.

All I did was put a simple toggle switch inline with the phone line going to the courtesy phone. Cut one of the wires for the phone line, put the switch in between it, then wire it all back up. Very simple, yet hours of fun.

Here’s a close up view of the switch.

Here it is all attached up to the wall.

So when he’d make a call I’d reach down, scratch my leg, and OOPS press the button. And he’d get disconnected.

I swear by the end of it he thought the phone was possessed and never came back!

Try it yourself!
