Description
The Knightsbridge FP4000BB is a 10AX 3-gang 2-way switch with a brushed brass flat plate finish, matching metal rockers, and a 2.5mm projection from the wall. The flat plate construction sits flush against the mounting surface without a raised bezel or surround, giving an 87.5mm square footprint that covers standard UK back boxes with minimal visual intrusion.
Designed for lighting control in residential and commercial settings, the switch provides three independent circuits with 2-way functionality on each gang. Two-way switching allows the same light or circuit to be controlled from two different locations in a room — typically used for stairs, hallways and larger living spaces where a single switch point would be impractical. The 10AX rating handles up to 2,300W per gang at 230V, suitable for domestic lighting loads including LED, halogen and incandescent bulbs.
The brushed brass finish is applied to premium-grade steel and shows a directional grain texture that softens reflections under artificial light. The matching brass rockers sit within defined black apertures on the faceplate, giving clear visual separation between each switch position. The plate requires a minimum 16mm mounting box depth and includes a built-in gasket to reduce dust ingress behind the plate. Certified to EN 60669-1 and backed by a 25-year warranty.

Frequently Asked
What does 2-way switching mean?
Two-way switching allows the same light or circuit to be controlled from two different switch locations. This is typically used on stairs, in hallways, or in larger rooms where a single switch point would be impractical. Each of the three gangs on this switch supports 2-way operation.
What back box depth is required?
A minimum 16mm back box depth is needed. The flat plate design adds only 2.5mm of projection from the wall once fitted, making it suitable for shallow mounting scenarios where deeper switches would not fit.
What's the maximum load per gang?
Each gang is rated at 10AX, which handles up to 2,300W per circuit at 230V. This is suitable for domestic lighting loads including LED, halogen and incandescent bulbs across multiple fittings on a single circuit.
What other finishes are available in this range?
Knightsbridge produces the flat plate series in multiple finishes including polished chrome, brushed chrome, polished brass, matt black and white. Use the search function or filters to find other variants in stock at Niori.
