Ethernet On Off Switch
As you can see, the ethernet switch just as a bunch of ports on it. So, to connect to the network what I have to do is first, take one of the ports that are already connected to the network,. Controlling an LED from an Arduino Web Page Button and a Push Button. Created on: 13 April 2015. This Arduino breadboard project uses an Arduino Uno and Arduino Ethernet shield with SD card as a web server. Two push button switches and two LEDs are connected to the Arduino. Ethernet Switch. Returning to our original topic of turning one ethernet cable into two, the ethernet switch is the real star of this guide. The way it works is incredibly simple. Whether you have a four-port switch or an eight-port one, you use one port to connect the switch to your router via ethernet, then the rest into the other ethernet.
Is it possible to place a switch in one of the four/five wires of an Ethernet cable that will disable it?
For my hardware project I would like the user to be able to disable the internet connection at the flick of a switch!
Notes
- I am aware that it will affect the speed and signal quality but with the hardware I am using it shouldn't matter.
- I know there are commercial options available on the market (like Just hit the Button) but at $50 and in a bulky branded box they are not suitable for my project!
Is this possible?

Have you got a physical switch that is rated for Cat5 cabling? The answer to your question is the same as the answer to my question.
More than likely you need to buy an electronic relay, and I know of some rated for Cat5.
Mike PenningtonMike PenningtonPartially serious, partially making light of the question, you could try a 4 pole, 2 throw (4PDT) switch like this one on Amazon and solder the switch in place in one of the wires in each pair.
It was released on December 28, 2004 in Japan and Hong Kong, followed by a release in North America on February 22, 2005 and in Europe on March 9, 2005.

In all seriousness though, Mike Pennington has the best solution with a button connected to a relay. Add a few RJ-45 jacks and the aforementioned items to a project box, and you've got a nice little physical network kill switch.
Edit: Had poles and throws mixed up. Updated Amazon link accordingly. Added edit edit.
Check out the cabling for Ethernet of twisted pair. If you're using 1000BASE-T (1 gig ethernet) then all four pairs are used for communication, so technically killing one pair would disable 1GE communication. However 10BASE-T or 100BASE-T (10/100mb ethernet) only require two pairs for communication, which could lead to a situation of you killing the wrong pair.
There are 8 wires, configured in 4 pairs.
A four Pole Single Throw or 4 Pole Double Throw (4PST or 4PDT) will work to disable any ethernet. Be sure to switch one wire in each pair, preferably the white with colored stripe. Here is a $3.55 switch that fits the bill. http://www.ebay.com/itm/1-MINI-TRAIN-TOGGLE-4PDT-4P2T-ON-ON-4-POLE-SWITCH-125-V-/380289420533?pt=LH_DefaultDomain_0&hash=item588b040cf5
Since this is a '2 Throw' or'DT' you could even wire another ethernet network to the unused poles to connect up to.
