Wireless Wall Switch Double Button

Two radio channels in a standard-size switch enclosure: this control lets you operate two separate 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. You will need 2 receiver modules — the Wireless Switch Module 10A 300W max (ref. WHD05) — order separately.

Technical details

• Type: radio wall transmitter, 2 buttons — 2 independent channels
• Radio protocol: 433.92 MHz, ASK modulation (amplitude coding)
• Power supply: 12V 27A battery — no wiring needed at the switch box
• Specified range: 100 m in open space
• Dimensions: 86 x 86 x 13 mm (standard 60 mm mounting-hole spacing)
• Housing: white PC polycarbonate
• Temperature range: -10°C to +70°C
• Compliance: CE & RoHs — 2-year warranty

Features

The two channels use distinct codes, so there is no risk of cross-control between the two receivers, even when installed in the same box. You can assign them as needed during pairing — to two separate circuits, or pair both buttons with the same receiver to add a second control point. Since the transmitter runs on a 12V 27A battery, it draws no power from the installation and does not affect any power calculations. The 433.92 MHz ASK transmission (amplitude coding) provides a useful range of around 100 m in open space.

Installation

Receiver modules must be ordered separately, one for each controlled circuit. Isolate the relevant circuits, connect each module to the live and neutral upstream of the load, restore power, then pair the left and right buttons in sequence — one channel at a time to prevent code crossover. Finish by mounting with double-sided adhesive or screws on a 60 mm box. No work on the existing switchgear is required.

Where can you use this wireless switch?

Suitable for commercial premises to separate general lighting from task lighting in the same open-plan area, for shops to control window and sales-floor lighting independently, at home to distinguish between a ceiling light and indirect lighting, or in an extended building with cladding where running cables to the control point is no longer feasible.
