KAV offers this 2-way ceiling switch. One of the terminals can be connected to either of the two, but not both at the same time. The advantage of a two-way switch is the ability to control a single device from two separate locations. A convenient and apt use for them is for locations like stairways, a long corridor or a very large room. So, imagine, it is late at night and you are at the bottom of a stairway. Features: Durable White Plastic Construction Raised Rounded Profile Screw Terminals Without Indicator Easy maintenance
