• Lighting and Equipment Grouping: Used with compatible multi-position step switches to manage stepped lighting scenes or specialized industrial equipment settings.

Buyer Guidance

• Verify Insert Compatibility: Ensure you have the correct underlying 3-step switch mechanism installed in the wall box, as this product is the centre plate and rotary knob cover only.

• Match Design Range: Confirm that your surrounding switch frames belong to the Berker R.1 or R.3 series to maintain a uniform aesthetic across your installation.

• Check Load Requirements: When planning your circuit, ensure the underlying switch insert matches the electrical current and voltage requirements of your connected motor or fan load.
