With its two channels, the ON/OFF Lighting Relay Switch enables the

user to connect and remotely control one or two lights with a wireless

and battery-free controller (wall switch, remote, …).

It is easy to install, without building work, behind a wired wall switch,

on the ceiling or in the electrical panel.
