At first glance, the quarter-turn twisted design seems strange, but this means that more than one fits perfectly together in a socket. This is because the holes for the plug are always slanted here, as shown in the image below. So if you place 3 WiDom plugs in the block shown, they will all sit neatly right next to each other.
The plug is equipped with a push button with which it can be switched on and off manually (as most plugs have). This button is also equipped with a small LED that works as an indicator. This can be used to see whether the plug is in the in or out modules or whether there is overload.
Something unique compared to other plugs is that the plug can also be used for scene activation of other devices by clicking the on / off button twice. How useful is that?
