[The Real Slim Shady]

Interesting... cheating... but interesting.

Just to be clear, its called an ethernet cable, and you could do this with the wires orange, orange+white, green, green+white on a Cat5 ethernet cable. If you did it with any of the other 4 wires it would have no effect as these are unused. On a Cat6 ethernet cables though with speeds up to 1gbps doing this may only reduce the speed. unsure tbh

but i will say doing this will severely compromise the quality of the cable. You may find that you have a reduced signal over the wire even when the switch isnt activated. it will be far more susceptible to interference from outside sources.
