Wireless Momentary switch help

Hello,
I am trying to figure out a way to wireless shut off my internet connection.

I am looking to make a normally closed wireless momentary switch so that when i hold the button down it will cut the connection and when I let it up the connection turns back on.

I know i could hack a wireless doorbell but aren't those normally open?
If i could reverse it somehow that would work i guess.

I would like to know how to make one cheaply if possible.

Please guide me thank you!!
