Self-powered wireless wall switch works: Self-powered wireless switches add a receiver to the connection between the light and the wire. The switch requires no wiring; inside the switch is a self-powered module that converts the kinetic energy generated by pressing into electromagnetic energy, which is then converted into electricity to drive the element. The device transmits an RF signal. The receiver turns the light on or off when it receives the signal. No wireless remote control required: wiring can be connected anywhere in the home without cutting through walls High-quality material with flame retardant: PC material is temperature and pressure resistant and has a long service life No need to connect to the power supply, no danger of electric shock, waterproof switch insulation can be touched by wet hands to keep away from the danger of electric shock. Receiver experimental parameters: Rated voltage: 95-260V Relay life: open/close times 400,000 Resistive load: 1500W Standby power consumption: 0.3W Inductive load: 1200W Working power consumption: 0.8W Capacitive load: 1200W Operating temperature: -20C~+70 Operating humidity: 80% Operating temperature rise: 15 Instruction manual 1.Setting and switch-off status Long press the receiver button for 3 seconds, the indicator light blinks once, release the button, and press the wall switch, the receiver indicator light blinks once, which indicates successful learning. 2. Setting on state (only for turning on the light) Long press the receiver button for 5 seconds, the indicator light blinks twice, release the button, press the wall switch once, the receiver indicator light blinks once, indicating successful learning. 3.Setting off state (only for turning off the light) Press and hold the receiver button for 7 seconds, the indicator light blinks 3 times, release the button, press the wall switch once, the receiver indicator light blinks once, indicating successful learning. 4. Clear the learning status. Long press the receiver button for 10 seconds, the indicator light blinks 4 times to indicate that all learning remotes are deleted. 5. Short press the receiver button, the relay will turn on or off every time you press it.
