This 900 series white moulded 20A 16AX single light switch from British General will operate one light in a room. 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). Its moulded white front-plate has a high resistance to fading discolouration and scratches, with inherent anti-microbial properties proven to reduce bacterial development and inhibit the growth of infectious diseases. Finished with classic square edges and screw caps for a sleek appearance.
