SWYAM Self-Powered Kinetic Wireless RF Switch – 3 Gang 3 Receiver 433MHz

The switch contains a miniature kinetic energy harvester, typically a piezoelectric element or electromagnetic generator. Each press of the button creates a small mechanical motion that is converted directly into electrical energy. This burst of power is sufficient to energize the onboard 433MHz RF transmitter circuit and send a wireless signal to the paired receiver, eliminating any need for batteries or wired power.

In open, unobstructed spaces, the reliable operating range can be up to 30-50 meters. Inside a typical home with interior walls, the effective range is generally 15-25 meters, as the 433MHz frequency offers good penetration through drywall and wood. Range can be reduced by significant metal obstructions or dense construction materials like reinforced concrete. For best results, ensure a relatively clear line-of-sight path between the switch and receiver locations.

Each receiver module has screw terminals for Live Input (L), Load Output (L OUT), and Neutral (N). First, turn off power at the circuit breaker. Connect the main AC supply Live and Neutral wires to the receiver's L and N terminals. Then, connect the wire going to your light or appliance (the load) to the L OUT terminal. The receiver can be tucked inside a switch back box, a ceiling rose, or a lighting fixture canopy. Ensure all connections are secure and insulated before restoring power.

Yes, this system supports 2-way (multi-way) switching. You would need additional compatible 433MHz transmitters (like extra kinetic switches or remote controls) programmed to the same RF code as the receiver. The pairing procedure typically involves pressing a learn button on the receiver and then activating the new transmitter. This allows you to control a single light from two, three, or more different switch locations without running any additional wires between them.

The receivers are designed for standard resistive and inductive AC loads. They are compatible with incandescent bulbs, halogen lamps (including low-voltage types with electronic transformers), LED bulbs, CFLs, ceiling fans, exhaust fans, water pumps, and similar appliances. Always check the receiver's maximum rated current (typically 5-10A) and ensure your connected load's power consumption does not exceed this limit to prevent overheating or failure.
