Hager universal stair switch WL0023, black — wall-mounted electrical switch for stair/auxiliary circuits

Hager WL0023 is a universal stair (two-way) wall-mounted electrical switch in a black finish, designed for manual control of stairway and auxiliary lighting circuits. The switch is intended for standard flush (in-wall) installation and supports two-way switching configurations to allow control of the same lighting point from two locations. Its compact design and neutral black colour make it suitable for residential and commercial interiors where simple, reliable switching is required.

Advantages

The switch provides two-way switching capability for stair and corridor lighting, enabling convenient control from multiple locations. Its wall-mounted, flush-install design fits standard back boxes and offers a consistent appearance with other wall devices. The black finish provides visual neutrality and can be integrated into modern interiors. The device is made to meet typical electrical installation requirements for manual lighting control and is compatible with common wiring schemes for two-way circuits.

Suitable for

• Staircase lighting in residential buildings
• Corridors and passageways in commercial premises
• Auxiliary or service lighting where two-way control is needed
• Retrofit or new construction projects with standard in-wall mounting

Key specifications

• Mounting type: flush wall-mounted installation
• Function: two-way (stair) switching for manual control
• Finish: black
• Wiring: compatible with standard two-way wiring schemes
