Attaching a rocker switch on RJ45 cable (crossover)

Hi, I'm planning to attach a rocker/toggle switch on RJ45 cable. I'm connecting two computers here directly with RJ45 crossover cables. I will use the rocker switch to cut the connection between the two computers. I know that there are 8 wires in the cable. The question is which pin should I connect to the switch to effectively disable the connection between the two computers?

there are eight wires but only 4 are really used, you would need to open two of them to disable traffic.

to disable Transmit, you need to open either pin 1 or pin2
to disable Receive, you need to open either pin3 or pin6
