[QUOTE="SPECIAL LOCATION, post: 519295, member: 250"] Your images show 2-way switches.. (NOT 3-way switches).. I think you are getting confused by the number of 'wires' to each switch.. not the number of 'ways' it can switch. i.e. A 1-way switch has TWO wires... 1x supply wire in and 1x switched supply out to a single load. (1-way) and a 2-way switch has THREE wires... 1x supply wire in and 2x switched supplies out, to swap the supply connection between one or two possible ways. (2-ways) {in your first image.. The red wire in L1 is swapped between the yellow wire L2 and blue wire L3, as you move the switch} If you had a a 2-gang 3-way switch you would have 8 connections not 6. as a 3-way switch would need 1x supply in and 3x switched outputs.. (4 terminals needed for 3-way). [An intermediate switch will have 2 pairs or 2 terminals, (that are crossed over each time you operate the switch) 4 wire connections).. The most important thing is want ProDave said... A lot of manufactures have a limited range of intermediate switches, and/or, some wholesalers / retailers don't stock the full range of available intermediate switches.. So 90%+ of the time it is much, much, much easier getting a 2-way switch to match the design of an intermediate switch... Than trying to match an intermediate switch to the design of the 2-way switch!!! Guinness [/QUOTE]
