Transform any home into a smart home with the Honeywell Z-Wave In-Wall Switch. The on/off switch replaces your current light switch, uses your existing wiring, and provides Z-Wave wireless and in-wall control of overhead lighting. The switch enables wireless control of on/off functions of direct wire incandescent, LED, xenon, halogen and fluorescent lighting. Providing ultimate flexibility, the Honeywell Z-Wave Switch allows you to operate the switch by itself or easily integrate the switch with two-way, three-way or four-way wiring configurations by adding the Honeywell Add-On switch. Single pole wiring configuration turns the light or appliance on/off from one location. Three-way wiring configuration turns the light on/off from two separate locations. Four-way wiring configuration turns the light on/off from three separate locations. The Honeywell Add-On Switch is required for Three-way or Four-way installations. The lighting control includes a blue LED indicator light to easily locate the switch in a dark room. Take control of your home lighting with Honeywell Z-Wave Smart Controls!
