Pressing the button of the Smartwares Wall Switch 2-channel Wireless sends a wireless signal to a Smartwares receiver. This way you create 2 buttons in locations where it is not possible to connect them to the electricity. You hang the switch yourself, without the help of an electrician. Set the button as light switch (also suitable for dimmers) or to operate a shutter. The switch can also be set as a timer, then the receiver automatically switches off again after a period you have set.
