Tuned for High-Speed Ceiling Fans: Specifically calibrated capacitive circuitry delivers steady low-end torque and smooth speed transitions, preventing motor stalling and buzzing in high-RPM ceiling fans.
Hum-Free & Energy Efficient: Eliminates the disruptive electromagnetic hum and excessive heat buildup associated with conventional resistive dimmers.
Positive Rotary Step Indexing: Features a tactile rotary dial with distinct mechanical step detents that prevent contact floating and speed drifting.
Dual Architectural Color Choices: Available in Metallic Silver (66504S) for bright, modern metallic switchboards and Graphite Black (66504GB) for glare-free, contemporary dark-toned walls.
Flame-Retardant Polymer Housing: Molded from self-extinguishing, impact-resistant thermoplastic engineered to withstand continuous operating temperatures across residential and commercial installations in Nepal.
