- 1.5" (38.1 mm) round x .5" (12.7 mm) deep plastic replacement knobs - all finishes except white and ivory are spray-painted (knobs only manufactured in white or ivory colors)
- dimmer knobs are brand / stem type specific - see image to determine your stem type
- try to find the brand name on the device itself to help identify which knob will work
- Leviton, Lutron, or Pass & Seymour / GE brand stem types; 3/8" (9.5 mm) internal depth
- Leviton - 7/32" (5.5 mm) diameter D-shaped stem; 3/8" internal depth
- Lutron - 7/32" (5.5 mm) diameter split stem; knob has C-shaped opening; 9/32" (7.1 mm) internal depth
- GE - 3/16" (4.8 mm) round split metal stem; replacement knob has circular opening with two wings - one fits into slot, other pushes outside edge to hold
- "Current GE Replacement" style will fit your old GE light dimmer device (but not low voltage master selector) and is the correct replacement for an "Old GE" knob
Some brands may not have name printed on device, so if you still don't see what you need, please see our Dimmer Knob Replacement Guide with photos of old dimmers if you have more questions.
GE note - older GE dimmer switches push in to turn lights on, then rotate to dim. This discontinued brand is found in older homes. The old style dimmer knob has a circular opening on back with tiny ridges inside that tended to strip over time. These current Pass & Seymour brand replacement knobs for GE dimmers are designed to be longer-lasting.
Vintage Low Voltage Systems: If you are trying to replace a GE knob for a on old low voltage 9 switch controller, then the Lutron knob is a better fit because the center stem is larger than those on a regular light dimmer.
Note: these knobs are about 1/2" (12.7 mm) deep and the dimmer stems push into the back of them about 5/16" (7.9 mm). The area where you push in the stem does not extend past the base of the knob. If you need extra long stems to fit down into a hole on vintage speakers or are trying to replace dimmers by other brands these may not fit. Please confirm whether you have at least 1/2" (12.7 mm) of stem protruding from your wall plate.
Choose your replacement rotary knob color based on the either the shade of your current electrical switches or the finish of your wall plates. Mixing and matching knobs to tie in other hardware or room furnishings is also a popular approach.
- a black dimmer switch knob will look particularly great on black, dark bronze, or stainless steel wall plates
- dark brown dimmer switch knobs are attractive when paired with dark wood, brown, bronze, and brass light switch covers
- almond, ivory, and white replacement dimmer switch knobs are good neutral colors for light switch plates in any color
