Double-Button Wireless Wall Switch
Two radio channels in a standard-size electrical fitting: this control lets you separate two lighting circuits from a single location without modifying the existing wiring. Each button is paired with its own 220V 10A receiver module (sold separately), installed as close as possible to the load. An effective retrofit solution when the electrical panel and conduits are already full.
⚠️ Receiver required, not included. This transmitter cannot control any load on its own. Allow for 2 receiver modules — the 10A 300W max Wireless Switch Module (ref. WHD05) — to be ordered separately.

Features
The two channels have distinct codes: no risk of cross-triggering between the two receivers, even when installed in the same box. Lassignment remains flexible during pairing - two separate circuits, or both buttons on a single receiver to double the control point. Since the transmitter runs on a 12V 27A battery, it draws no power from the installation and is not included in any power calculations. The 433.92 MHz transmission using ASK modulation (amplitude shift keying) provides a practical range of around 100 m in open areas.
Installation
Receiver modules must be ordered separately, one per controlled circuit. Isolate the relevant circuits, connect each module to the live and neutral wires upstream of the load, restore the power, then pair the left and right buttons in sequence—one channel at a time to avoid crossed codes. For final mounting, use double-sided tape or screws on a 60 mm box. No work on the existing electrical fittings is required.
Where should you use this wireless switch?
Useful in commercial premises to separate general and task lighting on the same floor, in retail to distinguish window displays from the sales area, in homes to distinguish ceiling lights from indirect lighting, or in an extension with cladding where running cables to the control point is no longer feasible.
