A two gang switch will be a swith witho the the shape of a duplex outlet. with a toggle on each end. there will be two screws on each side with possibly a green screw on one of the sides. The green screw is for ground, and should be either attached to the box or a green wire all the way back to the panel. The screws on one side will be a copper brown color and you will notice a strip of metal that connects the two screws together. This is the hot or common side (usually a black wire. The two screws on the other side will be a bright copper color, and they will be the swich leads from the switch to the fixture you are attempting to power up (the wires that connect to these switch leads are probably any color but green or white). Never connect the neutral (white) wire to any part of the switch.
The three way switch will have three screws on it. One is copper brown, and the other two are bright brass in color. The dark screw is the common (black wire). the other two screws connect the runners from one switch to the other switch. The runners dont connect to anything but the other switch. On one end the common wire attaches from the switch to the power and on the other end the common wire attaches from the switch to the fixture. The white (neutral) wire does not connect to the switches, it runs from the panel directly to the fixture.
I hope this has been helpful.
SOURCE: I need to wire a 3 gang switches in a 3 gang box
before u start make sure power is off before working with electrical lines ---start with the 12/2 coming into box black [power] white [ground-neutral] and u will have 3 separate lines for the lights so u will have 4 lines total coming in the box== with the 3 light lines take the white and strip back the plastic and connect [wire nut] all 3 to the 12/2 white line --now take the 12/2 black line and connect it to the first switch gold color screw- bottom screw -now take some wire about 2-3 inch strip both ends and connect from the 12/2 black wire connection on the switch and connect to the gold /bottom of switch 2 than do the same for switch 3 connecting the wire from switch 2 so u will have power feeding all 3 switches-- now connect the black lines for the lights to the other side of each switch and ur done

I am unsure what you mean by a 2 gang switch. There are single pole switches, one switch that turns a light on and off, for example, from one location. A 3-way switch turns a light, for example, on and off from two locations. There are also 4-way switches and they are used with 3-way switches. A single pole switch generally has two wires attached to the two brass colored screws on the switch: a black wire that is hot attaches to the "bottom" of the switch (the switch should have top stamped into it) and another black wire, which goes to the fixture itself, which is the switch leg attaches to the "top" of the switch. Please not that sometimes the color varies for the wires so be careful. Is this a newer home or older? If you respond to my clarification request and can send me a e-mail address I can send you a detailed drawing of both a single pole switch and a 3-way switch. Good luck!
