1-Channel RF Receiver 5A Relay Switch 433 MHz, Non-Dimmable Evoges Firefly EFF1CHRFSW

The Evoges Firefly EFF1CHRFSW is a compact RF-relay module designed to convert wireless RF signals into mains switching — letting you control lights or other circuits remotely, without new wiring or complex installation. It’s the “receiver” side of a wireless switch system: when paired with a compatible wireless transmitter (e.g. a kinetic or RF switch), the receiver handles the actual switching of the load, making it ideal for retrofits, renovations, or situations where running cables is impractical. 

Because the EFF1CHRFSW is non-dimmable and built for simple ON/OFF control, it’s especially suitable for standard lighting circuits, fans or appliances where dimming isn’t required. Its 5A relay provides enough capacity for typical household light fixtures or small loads, making it a versatile addition even to older wiring setups. 

Features & Benefits

• Wireless RF control (433 MHz) — enables remote switching of circuits without additional wiring or wall-chasing, ideal for retrofits or flexible installation layouts. 
• 5A relay output — supports common loads such as lighting circuits or small appliances (e.g. ~300W LED load / 800W resistive load) — sufficient for many domestic applications. 
• Non-dimmable ON/OFF switching — simple, reliable activation and deactivation of the circuit without complications of dimming electronics. 
• Compact and discreet form — small relay module (not an entire switch plate) — can be installed wholly behind fittings or within a ceiling void / switch-box, keeping the visible installation minimal. 
• Flexible pairing: works with RF or kinetic switches — pairs with wireless / battery-free transmitters from the same product line, offering user-friendly retrofit or new-build options without needing neutral wiring. 
• Ease of installation — avoids intrusive rewiring: ideal when you want to add a new switch point, retrofit to plastered walls, or enable remote control without rewiring entire circuits.
