## Long description

Kontakt-Simon BMS9T.01/11 is a white rotary dimmer for single-channel control of mains AC lighting. It provides manual, stepless adjustment of light intensity via a rotary knob and is intended for use in residential and commercial interiors where straightforward, local dimming is required. The compact white design integrates with a variety of décors while the control principle allows gradual brightness changes for visual comfort.
Advantages
The rotary control enables continuous, smooth dimming without preset steps, allowing fine tuning of light level. The unit is designed for simple wall mounting and intuitive operation by turning the knob. Its white finish blends discreetly into most interiors, and the single-channel configuration keeps wiring and operation simple for one lighting circuit.
Suitable for
 Living rooms and bedrooms where adjustable ambient lighting is required
 Hospitality areas such as hotel rooms or dining spaces for mood control
 Single-circuit lighting zones with compatible incandescent, halogen, or dimmable LED loads
 Renovation projects requiring a compact, neutral-colour rotary dimmer
When it may not be suitable
This dimmer is intended for single-channel mains AC circuits and may not be suitable for multi-channel or centralized lighting control systems. Compatibility depends on the type of lamp load; some electronic transformers, non-dimmable LED drivers, or specialized fixtures may not work correctly and can cause flicker or reduced dimming range.
Key specifications
 Control type: rotary, stepless manual dimming
 Channels: single-channel (one circuit)
 Mounting: wall-mounted, flush or surface depending on installation accessories
 Finish: white
 Supply: mains AC
 Compatible loads: incandescent, halogen, dimmable LED (subject to load compatibility)
How to use
Install the dimmer in place of a standard wall switch following local electrical regulations and the instructions of a qualified electrician. After power is connected, rotate the knob clockwise to increase brightness and counterclockwise to decrease it. Adjust smoothly to the desired light level; a full turn may switch the circuit on or off depending on model behaviour.
What to consider before purchase
 Verify lamp types and driver compatibility; non-dimmable LEDs and some transformers may be incompatible
 Check mains voltage and installation requirements against local electrical standards
 Confirm single-channel control meets your zoning needs or whether multi-channel control is required
 Ensure mounting style and dimensions fit existing wall boxes or plan for adapter plates if needed
Usage recommendations
For best performance with LED loads, test the dimmer with the intended lamps before final installation. Use compatible dimmable LED lamps or drivers rated for leading/trailing edge dimming as specified by lamp and driver manufacturers.
