This British General screwless, flat profile switch is cleverly designed to secure to the wall with screws concealed in the back plate giving it a clean look. The clip on front plate sits flush to the wall, adding to the sleek aesthetic. This is a two gang, two way device and you can use it to operate two separate circuits or fixtures from the same plate. Two way switches like these are commonly used on stairways so you can operate the same light from the top and bottom.
