Suitable for most ventilation fans in kitchens or bathrooms, the FBS15 has an extremely thin plate (under 5mm thick from wall to face), flat profile, rounded edges and stylish brushed steel finish that suits a wide range of interior decor. With no visible plastic around the switch it stays looking clean and modern for longer. Its Clip On, Clip Off front plate design is secure and easy to use, and the socket itself can also be easily retrofitted into existing backboxes (minimum 16mm depth required). The switch also has backed out captive screws to further aid simplify installation. While constructed with a triple-pole switching design, if required it can be used for double pole applications. Furthermore, the FBS15 is fitted with a moisture-control gasket which enables it to be installed into recently plastered walls without the risk of tarnishing the finish. As standard on all BG sockets and switches, the FBS15 comes with a 25-year guarantee for peace of mind.
