They are called double pole single throw switches. DPST for short. The poles are how many separate isolated switches there are, and the throws are how many positions you can set the switches to. Thus, you can get
3P4T switches which contain three separate switches, all controlled by the same movement, which can each be set to one of 4 possible connections.You may only be able to get double pole double throw (DPDT) switches, but they will work too.
Greetings. I have three IDE ATA hard drives in my computer. I want to be able to turn each drive off or on without having to take the cover off the computer. So I'd like to install toggle switches on the front of the case. Only problem is hard drives have two power rails, 12vdc and 5vdc. Seems that most switches are setup to handle just one voltage, not two. What kind of switch should I be looking for? Many thanks.

You shouldn't leave an unpowered drive on the cable. This will be a bigger problem than switching the power.
