3 gang switch and you can call it 2-way switch..is a type of swithces we are using mostly in the stairs lighting ,that mean you have switch up to the stair and one down to the stair and you can switch the light on from one and switch it off from the other switch and via verse. <<>> There is no such thing as a three gang three way switch,. The nearest thing is a three gang double throw switch. It is used to supply a three phase load from two individual three phase supply sources. This is the type of manual switch that can be used for emergency power switch over from utility to generator. Three way switching uses a single pole double throw switch at each end of the circuit and a cross over switch in the center position. The center switch in a three way lighting configuration is a cross over switch and a double pole double throw switch in that position will not work.
