Add a light switch exactly where you need it with the Ener-J PRO Series 1 Gang Wireless Kinetic Switch in white. A built-in micro energy generator turns each press into power and sends an RF 433MHz signal to your Ener-J receiver - so there are no batteries, no wires, no back box and no channelling into walls. Fix it to a painted wall, glass, marble, ceramic tile or any smooth surface and move it whenever you like. The IP65 waterproof design is safe to use in bathrooms, as the switch is volt-free. Pair one receiver with up to 10 switches for 2-way, 3-way or multi-way switching, or let one switch control an unlimited number of receivers. With a dimmable receiver (WS1038 or WS1039) you get stepless dimming with brightness memory, and a WiFi receiver (WS1037, WS1038 or WS1048X) adds app control. Specification: 1 Gang, white.
