Does the Shelly Wall Switch 1 Black work on its own?

No. It is a passive front with no electronics; to control a light or socket it needs a Shelly relay (Plus 1/1PM/2PM or Gen3/Gen4) mounted behind it and wired to the SW input. The relay is sold separately.

Which Shelly relays is it compatible with?

Three holders are included: holder 1 for Shelly 1/1PM, holder 2 for all Shelly Plus devices and Gen3 (1, 1PM, 2PM, i4, Dimmer, DALI Dimmer) plus Gen4 (1, 1PM), and holder 3 for Shelly 1L and Dimmer 2.

How many buttons does it have and what size is it?

It has a single button. The front measures 70×70×12 mm without the holder and fits a standard wall back box.

Does it need a neutral wire or its own power?

No. The panel is not powered: it only closes the relay's low-voltage SW input (max 12 V DC / 18 V AC, 50 mA). The 230 V supply is handled by the Shelly relay behind it.

Who should carry out the installation?

The 230 V back-box installation should be done by an electrician, because the Shelly relay behind it works with mains. CasaSmart offers a free consultation, while design and on-site visits are paid services.

Can I use a black panel with a white frame or vice versa?

Yes. The black panel is a separate part and can be combined with Shelly frames of a different colour; choose the frame colour to match your Chisinau interior.

About this product

The Shelly Wall Switch 1 Black is a passive single-button front for a Shelly relay hidden in the wall box. It holds no electronics and no radio: the panel simply closes the relay's low-voltage SW input, so the actual control of a light or socket is handled by the Shelly module mounted behind it.<br><br>The black plastic body measures 70×70×12 mm (without holder) and fits a standard back box without widening the wall or rewiring. Three interchangeable holders are included: holder 1 for Shelly 1/1PM, holder 2 for all Shelly Plus devices and the Gen3 range (1, 1PM, 2PM, i4, Dimmer, DALI Dimmer) plus Gen4 (1, 1PM), and holder 3 for Shelly 1L and Dimmer 2.<br><br>The operating temperature is −20 °C to +70 °C, the maximum switched voltage is 12 V DC / 18 V AC, and the current is up to 50 mA. A Shelly relay is purchased separately.

Where it works

Use cases

In a Chisinau flat living room a Shelly Plus 1PM behind the panel switches the chandelier; pressing the rocker turns on the light even without internet.

The black rocker replaces the old switch and closes the SW input of a Shelly relay hidden in the back box.

In a bedroom with graphite finishes the panel pairs with a black frame and blends into the wall.

The black plastic matches dark frames and panels where a white switch would look out of place.

When updating the hallway of a private house, the old switch is swapped for the passive Shelly panel without chasing the walls.

The 70×70×12 mm front fits a standard back box and covers the cable already in place.
