Description
The Knightsbridge 20A 1-gang DP switch provides double-pole switching rated for 20A loads, designed for controlling fixed appliances such as water heaters, immersion heaters and dedicated circuits where full isolation is required. The switch features a neon indicator above the rocker that illuminates when the circuit is live, providing at-a-glance status confirmation. The brushed brass flat plate is constructed from premium-grade steel with a directional brushed finish and measures 87.5mm square with a minimal 2.5mm projection from the wall.
The double-pole switching isolates both live and neutral conductors when in the off position, offering safer isolation than single-pole switching for high-draw fixed appliances. This makes it appropriate for dedicated circuits serving immersion heaters, electric showers, instantaneous water heaters, and similar permanent installations where the appliance is not routinely unplugged. The neon indicator draws minimal current and confirms power is reaching the switch even when the load is off, which is particularly useful for appliances housed in cupboards or remote locations.
The flat plate design sits nearly flush to the wall surface with an integrated gasket behind the plate edge that helps seal the gap between plate and plaster. The brushed brass finish provides a warm metallic accent that complements both traditional brass fixtures and warmer-toned contemporary interiors. The rocker is colour-matched to the faceplate, maintaining a unified appearance. The switch is certified to EN 60669-1 and carries a 25-year warranty, reflecting Knightsbridge's confidence in the construction quality and contact durability.

Frequently Asked
What is double-pole switching and why does it matter?
Double-pole switching isolates both the live and neutral conductors when the switch is off, providing full circuit isolation rather than just breaking the live wire. This is safer for fixed appliances like water heaters and immersion heaters, as it ensures no current can flow through the appliance even if a neutral fault develops elsewhere in the installation.
What does the neon indicator show?
The neon indicator illuminates when mains voltage is present at the switch terminals, regardless of whether the switch rocker is in the on or off position. This confirms the circuit is live and allows quick visual confirmation of power availability, particularly useful for appliances in cupboards or remote locations.
What back box depth is required?
A 25mm minimum back box depth is needed for safe installation. The flat plate adds just 2.5mm projection from the wall surface once fitted, giving a total depth of approximately 27.5mm including the faceplate.
What other finishes are available in this range?
Knightsbridge produces this flat plate switch style 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.
