No, these are designed specifically for rotary dimmers with a 5mm diameter potentiometer shaft, not for standard toggle or rocker light switches.
No, these knobs are made of non-conductive plastic, making them safe for use on electrical controls.
Yes, provided the potentiometer shaft on the audio equipment is exactly 5mm in diameter.
No, these are push-on style knobs and do not require set screws.
The knob measures 16mm in height.
Ensure the shaft diameter is exactly 5mm. If the shaft is slightly undersized, apply a small amount of adhesive or a shim to create a tighter fit.
Check if there is debris inside the knob cavity or if the dimmer shaft is mounted too far outward from the wall box.
To install, ensure your dimmer switch is turned off. Align the opening of the knob with the 5mm shaft and press down firmly until the knob is seated against the faceplate. Avoid using excessive force to prevent bending the internal potentiometer shaft. To clean, use a soft, dry cloth; avoid using harsh chemical cleaners or solvents, as these may cause the plastic to degrade or lose its finish over time.
