Berker 30763525 W.1 Surface-Mounted Illuminated Changeover Switch, Grey

For installations that demand both resilience and clear visual feedback, the Berker 30763525 changeover switch brings a sealed, surface-mounted design with an integrated neon indicator. Unlike standard flush-mounted switches that leave wiring exposed or require deep boxes, this W.1 series unit mounts directly onto the wall and carries an IP55 rating, making it a dependable choice for damp rooms, covered outdoor areas, and utility spaces where dust and moisture are present. The grey thermoplastic body is UV-stabilized and halogen-free, so it holds its colour and mechanical integrity even under prolonged exposure to sunlight or harsh cleaning agents.

Highlights

• 1-pole changeover (two-way) switching with 10 AX rating for resistive and inductive loads up to 250 V AC.
• Integrated neon indicator lamp glows when the circuit is energized, providing at-a-glance status in dark or remote locations.
• Surface-mounted (AP) construction with full sealing gasket and IP55 ingress protection for damp and outdoor environments.
• Robust UV-stabilized, halogen-free thermoplastic housing in grey (W.1 series).
• Screw terminals accept conductors up to 2.5 mm², ensuring secure, maintenance-free connections.

In daily use

The illuminated rocker gives immediate confirmation that the connected load—such as a porch light, cellar lamp, or workshop circuit—is live, eliminating guesswork when switching from a distance. Its changeover function allows control from two locations when paired with a second changeover switch, making it ideal for staircases, corridors, or long hallways. The surface-mounted base simplifies retrofitting onto existing conduits or solid walls without chasing, while the sealed full plate and gasket keep out dust, splashes, and insects. The grey finish blends discreetly into concrete, plaster, or industrial backdrops, and the switch remains easy to clean thanks to its smooth, non-porous surface.
