Wired keypad light switches connect to the lighting system through in-wall wiring, such as a centralized lighting bus, and typically use a dedicated low-voltage power supply. Wireless keypad light switches communicate over a Zigbee 3.0 network and can use line-voltage or low-voltage power, which can simplify placement where control wiring is limited.

Keypad light switches support configurable layouts, typically ranging from two to seven buttons with multiple button sizes and layout options, depending on the model. Buttons can control lights, scenes, music, security devices, shades, garage doors, and other connected functions, while some models also combine keypad control with dimming for one or two loads or support three-way control through existing wiring.

Before installing keypad light switches, verify the available wiring, including a neutral where required, existing three-way wiring for auxiliary control, and whether the device uses line voltage, a centralized 48V bus, or a specified DC power supply. Confirm the circuit voltage and load type, such as dimmable or non-dimmable lighting, and check compatibility with incandescent, halogen, electronic low-voltage, magnetic low-voltage, or LED loads as applicable.

Yes, keypad light switches can be configured to trigger scenes and control connected devices such as security systems, music, garage doors, and shades, in addition to lighting. Button layouts and backlit labels can help installers create intuitive controls for each system.
