Single-Button Wireless Wall Switch
On a renovation project, adding a control point often means chasing, filling, and repainting. This single-button radio transmitter eliminates that step: it sends a signal to a 220V 10A receiver module (sold separately), installed downstream in the recessed box or as close as possible to the light fixture. No changes to the existing circuit and no extra wires to run through the conduits.
⚠️ Receiver required, not included. This transmitter cannot control a load on its own. You will need 1 receiver module - the 10A 300W max Wireless Switch Module (ref. WHD05) - ordered separately.

Features
The button controls a single channel, paired by code with the receiver module. L’transmitter remains electrically passive: it is neither connected to the mains nor earthed, so it falls outside the NF C 15-100 wiring requirements applicable to recessed electrical fittings. All live components are housed in the receiver, wired according to standard practice. The 433.92 MHz ASK-modulated signal works well through drywall and standard-thickness concrete floors. Multiple transmitters can share the same code to create a wireless two-way switch.
Installation
Receiver not included: provide one compatible 433 MHz 220V 10A module per controlled circuit. Isolate the circuit at the electrical panel, connect the module upstream of the load (live, neutral, load output), restore power, then start pairing using the coding button. The plate can then be attached with double-sided adhesive to a smooth surface - tile, glass, or wall lining - or screwed onto an existing 60 mm box. Allow a few minutes per control point.
Where can you use this wireless switch?
Quick solution for apartment renovations, commercial property refurbishments, and load-bearing or stone walls where chasing is not an option. Also useful for adding a remote control in the back of a stockroom, in a workshop, shared garage, utility room, or office partition installed later.
