White Flat Knobs

White Flat Knobs are low-profile control knobs for panel-mounted thermostats, rotary switches, and appliance control panels. The flat top and white finish suit light-colored equipment housings, while the knurled edge provides a defined grip for manual adjustment.

The rear mounting configuration connects the knob to the shaft or spindle of the related control device. A printed or molded scale plate can be used to provide a visible reference for temperature or setting adjustment.

White Flat Knobs Advantages
Consistent Light-Color Panel Design

The white finish provides a practical option for control panels and appliance housings where a black knob would create a strong color contrast. It helps maintain a consistent appearance across the control area.

Low-Profile Panel Configuration

The flat top keeps the knob profile close to the panel surface. This is suitable for equipment designs where front-panel space or clearance is limited.

Defined Rotary Grip

The knurled edge provides multiple contact points around the knob, giving the operator a clear grip when turning the control for temperature or setting adjustment.

Clear Setting Reference

The flat top provides a suitable surface for printed setting information, while a matching scale plate can show the relationship between the knob position and the selected setting.

Suitable for Different Control Shafts

The rear mounting design can accommodate different shaft configurations, including D-shafts, round shafts, and knurled shafts, according to the connected control device.


White Flat Knobs Applications

White Flat Knobs are used on control panels where a low-profile rotary knob is required in a light-colored finish.

Water heater and heating equipment thermostats
Household and commercial appliance control panels
Appliances with white or light-colored housings
Industrial control panels and rotary switches
Equipment requiring a printed-scale adjustment knob

White Flat Knobs FAQ
What should be checked before selecting a White Flat Knob?

The main points are the available panel space, knob diameter, shaft dimensions, mounting position, and the required setting scale. These details determine whether the knob matches the existing control assembly.

How does the rear mounting affect knob installation?

The knob attaches from the rear to the shaft or spindle of the connected control. The mounting position should be checked against the shaft location and available space behind the panel.

What information is needed to match a replacement knob?

A physical sample, drawing, or the existing knob dimensions can be used for comparison. Shaft type, diameter, mounting details, and scale layout are useful for confirming the replacement specification.

Can the printed scale correspond to different temperature ranges?

Yes. The printed scale can be arranged according to the setting range of the connected thermostat or control device.

Are different knob diameters available for the same control type?

Different diameters can be considered where the control shaft and panel layout permit. The required diameter should be confirmed together with the available installation space.

Can White Flat Knobs be used with an existing thermostat assembly?

Yes. The knob can be matched to an existing thermostat when the shaft, mounting arrangement, diameter, and setting reference are compatible.

What is required for an OEM White Flat Knobs project?

A drawing, reference sample, target dimensions, shaft information, scale requirements, and estimated order quantity can be provided for specification review.

What order quantities can a Factory Supplier support?

The Factory can review sample requirements, trial orders, OEM production, and repeat Wholesale orders according to the product specification and quantity.
