## Long description

MONTIS WP-5A SIMPLEX MT052S is a 1-pole stair installation switch engineered for controlling lighting circuits in stairwells, corridors and communal areas. The mechanical design supports two-way (pass-through) operation, enabling switching from two different points. The switch fits into standard recessed installation boxes and provides reliable manual on/off control for a variety of lighting loads.
Advantages
The single-pole mechanical construction ensures straightforward operation and long service life under normal residential and commercial use. Two-way switching capability allows flexible control of lighting from multiple locations, improving usability in multi-entrance spaces. The unit is compatible with conventional incandescent and halogen lamps and with many LED drivers that support mechanical switching, making it suitable for retrofit and new installations where a simple, robust switch is required.
Suitable for
Stairwells and landings in apartment buildings
Corridors and hallways in offices and public buildings
Shared spaces such as basements, garages and utility rooms
Retrofit projects replacing standard mechanical switches
Key specifications

How to use
