Sequin Knobs Advantages
Distinctive Control Panel Appearance
The metallic sparkle-effect top gives Sequin Knobs a clear visual difference from plain molded knobs. The star or cross pattern can also create a recognizable control point on the panel.
Defined Grip for Rotary Adjustment
The knurled edge provides multiple contact points around the knob, giving the operator a defined grip when turning the control.
Clear Setting Reference
The top marking and matching scale plate provide a visible reference between the knob position and the selected temperature or control setting.
Coordinated Knob and Scale Design
The black knob body and black scale plate form a consistent control area, while the metallic top insert provides visual separation from the surrounding panel.
Easy Control Identification
The combination of the metallic top, patterned surface, and knurled edge makes the control visually distinct from standard plain-top knobs used on the same or similar panels.

Sequin Knobs are used on appliance and equipment control panels where a decorative top finish is required together with manual rotary control.
