The Wattstopper RT2BK is a Radiant 4-button digital timer switch rated for 0600W and 1/6 HP, providing automatic shutoff control for lighting and motor loads in commercial and residential installations. The 4-button interface allows selection of preset countdown intervals for hands-free load management, with a black finish that integrates with the full Radiant designer switch and wallplate system. Compatible with standard single-gang wallboxes, it replaces conventional toggle switches where timed occupancy control is required.
