Vlinca VBA-RCS4 Rotary Knob Wireless Dimmer

The Vlinca VBA-RCS4 is a premium rechargeable wireless dimmer with a smooth, high-quality rotary action that connects directly to the Casambi mesh. Mount it anywhere — furniture, desk surfaces, bedside tables, display cases — with no wiring and no backbox. Rotate to continuously dim lights, press one of the four preset scene buttons, or click the knob to toggle. Charges via USB-C. Where traditional dimmers need a fixed wall plate and a mains connection, the VBA-RCS4 needs neither.

Key Benefits

Why specify the Vlinca Rotary Knob

Analogue feel, digital precision

The Vlinca's high-quality rotary mechanism provides the satisfying tactile response of an analogue dimmer dial while transmitting precise digital dimming commands over the Casambi mesh. No steppy or sluggish response — smooth, continuous dimming from 100% to minimum across the full travel.

Place it anywhere

Furniture-integrated dimming for hospitality: mount a Vlinca on a bedside table, a restaurant booth partition, or a display plinth. USB-C rechargeable and wire-free — no visible cabling, no wall cut-outs, and no electrician required for placement changes.

Click to toggle scenes

In addition to rotary dimming, a click of the knob triggers the next configured scene or toggles the assigned group on/off. A single-hand, single-action control that replaces the need for a separate button in many residential and hospitality applications.
