This 20A triple light switch can operate 3 different lights, whilst the 2-way switching allows a second switch to be added to the circuit to operate the same light from another location (e.g. at the top and bottom of the stairs). This switch has a polished chrome finish screw-less flat plate with rounded edges that clips on and off making it ideal for modern interiors, whilst the moisture control gasket protects the metal from tarnishing.
