The Shelly Wall Switch 2 in black is a passive physical front with two buttons, designed as the visible face of a Shelly relay hidden inside the wall box. The panel has no electronics of its own and is not powered: the two buttons wire to the SW inputs of the relay, while the actual switching is done by the Shelly relay. This keeps the familiar feel of a wall switch, yet the circuit becomes controllable from the Shelly Smart Control app and through automated scenes.<br><br>The housing is made of matte black plastic in a compact 70x70x12 mm format without the holder, fitting standard back boxes. The kit includes three plastic mounting holders plus screws, giving compatibility with a wide range of Shelly relays: Shelly 2.5, the Plus, Gen3 and Gen4 series devices, as well as Shelly 1L and Dimmer 2. The contacts are rated for a maximum 12 V DC / 18 V AC and a maximum current of 50 mA, values typical of a control input rather than a power circuit.<br><br>For homes in Chisinau and across Moldova it is a discreet way to make an existing switch smart: place the relay behind the panel and control lighting or blinds both from the wall and remotely.
