Metal dimmer switches that require a neutral wire connect to the circuit’s line, load, neutral, and ground conductors, while models without a neutral wire are designed for locations where no neutral conductor is available. Before installation, confirm the dimmer’s load type and capacity, since no-neutral models may have different application requirements than neutral-wire models.

Many metal dimmer switches are available in wired and wireless configurations, giving installers flexibility for new construction, retrofits, and smart lighting upgrades. Wireless models may use Zigbee 3.0, so verify that the lighting control system supports the required network before installation.

Metal dimmer switches with premium metal faceplates require the appropriate mounting plate, which is supplied with the faceplate, while the faceplate itself must be ordered separately. Installers should follow the wiring requirements for the selected dimmer, since some models require a neutral wire and others support no-neutral installation, and use the included baseplate and screw-in terminals for device mounting and connections.

Choose metal dimmer switches with 0-10V control for four-wire 0-10V or 1-10V LED fixtures and dimmable fluorescent ballasts, with a built-in relay for separate on/off control when needed. Choose motion detection for occupancy- or vacancy-controlled lighting in bathrooms, closets, garages, or utility rooms, and choose dual-load operation when one device needs to control two lighting loads, including one dimmable and one non-dimmable load.
