230V Wireless Switch, 10A 433MHz Wireless Two-Way Switch, Battery-Free Radio Controlled Lighting Switch, 30M Range, No Wiring Required, 1 Receiver, 3 Controllers WHD05+WHZ03

【Wireless Switch】: This wireless light switch uses 433 MHz radio frequency technology, offering a transmission range of 30 meters indoors and 100 meters outdoors, reliably penetrating walls and floors. No wiring is required between the lights and switches, ensuring stable performance, strong anti-interference capabilities, and a fast, lag-free response. Its reliability surpasses that of WiFi-dependent systems. 【Self-Powered Design】: This wireless two-way switch incorporates an internal self-powering mechanism. Each press generates its own electricity, eliminating the need for external power sources or batteries. This removes the hassle and cost of battery replacement, providing an energy-saving, environmentally friendly, and worry-free solution. The built-in 433 MHz radio signal ensures instant light response at the touch of a button. [Convenient Installation]: The wireless two-way switch itself requires no wiring. It can be attached to any surface (such as walls, glass, or furniture) using adhesive or screws. The receiver connects to the live and neutral wires of the desired light fixture and pairs instantly for use. This wiring solution eliminates the hassle of wiring and reduces installation costs, making it ideal for apartments and older buildings. [Wide Voltage Receiver]: Rated voltage: 100-250V AC, rated current: 10A. The compact wireless switch kit fits easily into ceiling fixtures, switch boxes, junction boxes, and other control boxes. A single receiver can connect multiple switches, making it particularly suitable for staircases, bedrooms, or complex lighting scenarios.
【Important Note】: Wireless switches and relay receivers must be used as matching sets. Receivers and switches cannot be purchased separately, and receivers of different models cannot be connected to different transmitters.
