The Auto-On/Auto-Off SensaSwitch® provides convenient lighting control by responding to your presence through motion-sensing technology. Use this motion sensor light switch on its own to control a light or fixture from a single location, or pair with additional switches to control a single light source from multiple locations (3 or 4-way applications). This switch* features enduring Microban® antimicrobial technology that works to reduce the growth of bacteria, around the clock, for the lifespan of the product.
