hi. i have a related question. i would like to connect the switch to a relay, that i can control remotely. unfortunately i'm a total noob when it comes to electronics. i understand that i can solder two wires to the switch, without having to desolder the switch. but why does the switch have 3 pins, not 2? which ones do i solder? it should be really simple but i'm scared of ruining the main board. please advise.
