As both a transmitter and a receiver, the PCS SimpleWorx Wall Switch Transceiver Relay (120V/15A) supports a variety of remote control configurations. The switch controls a local electrical load just like a traditional wall switch. The locally connected load can be controlled with the switch (top rocker for ON, bottom rocker for OFF), or with a SimpleWorx remote transmitter. The switch can also send commands to an infinite number of SimpleWorx receivers. For example, you could wire a light to the Wall Switch Transceiver and link the Transceiver to a SimpleWorx receiver. Then, you could use another SimpleWorx transmitter to remotely turn on the light connected to the Transceiver, as well as the secondary receiver. An ON command from the transmitter would be received by the Transceiver and then passed onto the receiver. FEATURES: Controls a local electrical load up to 15 Amps. Sends commands to an infinite number of receivers. Accepts and relays commands from up to eight transmitters. Suitable for three-way switch applications. Mounts in a standard electrical box. NOTE: Requires a SimpleWorx transmitter and/or receiver for remote control applications. Manufacturer Part #: WSXR-15-W. Color: White.
