This cooker switch is fitted with an integrated moisture-control gasket which allows the switch to be installed into a recently plastered wall without the finish tarnishing. It also features a flush neon which adds visibility in enclosed areas. The NBS72 can be easily retrofitted into an existing backbox (47mm minimum box depth required) and is supplied with colour matched fixing screws, backed-out captive screws, and fitting instructions to ensure an easy installation. • Top quality Brushed Steel finish - lightly lacquered to prevent finger marks.
