The Crestron CLW-SW1A is a single-button, wireless wall switch designed as a standalone control device within the Crestron infiNET EX wireless ecosystem. This minimalist device provides a dedicated, single-function control point for lighting or automation scenes without the need for traditional AC wiring at the switch location. It is engineered for maximum installation flexibility, allowing it to be placed virtually anywhere on a wall using its included battery power and a standard single-gang wall plate. The single programmable button can be configured to perform a wide range of functions, from simple on/off control of a lighting load (via a compatible infiNET EX dimmer or relay) to triggering complex multi-device scenes that adjust lighting, shades, and temperature with a single press. This makes it an ideal solution for adding convenient control points in retrofits, renovations, or new construction where running new wires is costly or impractical.

The switch features a clean, modern aesthetic with a backlit button that provides visual feedback, often indicating status through its illumination. It operates on the robust and low-power infiNET EX wireless protocol, which creates a reliable mesh network with other Crestron devices, ensuring consistent communication even in challenging RF environments. Powered by two standard AA batteries, the CLW-SW1A boasts an exceptionally long battery life—typically several years—due to the efficiency of the infiNET EX protocol. The device installs into a standard single-gang electrical box and is compatible with Crestron's screwless wall plate system for a professional, finished appearance.

As a focused control interface, the CLW-SW1A exemplifies Crestron's approach to simplified, user-centric automation. It provides homeowners and building managers with an intuitive, reliable way to activate frequently used functions from a specific location, such as turning on a porch light from a garage entry or activating a "movie" scene next to a home theater seat. Programmed by a Crestron dealer using dedicated software, its function is fully integrated into the broader home automation system. This switch combines the convenience of wireless technology with the tactile certainty of a physical button, offering a discreet yet powerful tool for enhancing daily routines through automated control.
