If you would like to install your Brilliant in a multi-way configuration, but you currently have a dimmer as the other switch, you can easily replace the dimmer with a non-dimming switch.
You can find a three-way switch at your local hardware store or on Amazon. Make sure you purchase an appropriate switch for your multi-way set-up (three-way or four-way). A three-way switch will typically have four screws where you can attach wires, one of which is the ground screw. A four-way switch will have 5 screws where you can attach wires, one of which is the ground screw.
When you are replacing your dimmer, we recommend labelling your wires before installing your new on/off switch. You can refer to our article here on some common switches and dimmers and how they are wired.
