I am confused at what to purchase to replace a 3 light switch and one of the lights is 2 way. It gives me the option of 2G 2 way, 3G 2 way or 4G 2way. Which do I need to purchase?

Are you in the UK or the USA? E.g what do you mean by a "2 way" –  Walker Dec 28 '11 at 22:36
    
You have to replace a swich with a like kind. What are you talking about? 3 way, 4 way? –  shirlock homes Dec 28 '11 at 23:05
    
Are you in North America or somewhere else? How many lights are there? How many switches are there? Do you need to replace a light or a switch? What thing is it that is giving you these options? –  Skaperen Dec 29 '11 at 5:34
    
G stands for Gang, which is the number of switches. So if you currently have 3 switches, you'll need to get a 3G to replace the current one. I'm not familiar with European wiring methods and products, so I can't offer much help beyond that. –  Tester101 Dec 29 '11 at 12:54
