You will almost never work on anything 1000 volts as an electrician unless you work for a power supply company. So most people will probably have a normal single pole switch over a smaller sized switch. Normally you would not send a voltage through a switch, in this case you are only sending a small amount as it is only connected to an Ethernet cable. All I'm saying is a normal Single-pole switch is more common to find or buy from where ever (home depot, radio shack, etc.) then having to look specifically for a smaller size switch (although it would still work both ways, as long as it is not too small).
