433 MHz RF Wireless Remote Control Switch — 2Relay Receiver Key benefits Reliable remote switching: 433 MHz RF control with reception sensitivity (>97 dBm) for stable performance and strong signal penetration through walls, floors, and doors. Flexible control modes: Choose momentary, toggle (default), or latched operation to match different control needs without extra tools. Independent dual outputs: Two independent relays let you control two circuits separately from a single receiver. Broad compatibility and multidevice control: Each receiver can store about 20 transmitters; one transmitter can operate multiple matched receivers. Durable, safe switching: quality relays rated for over 100,000 cycles and robust blue power terminals rated up to 10 A. Works across common AC voltages (85 V–250 V, compatible with 110 V/120 V/220 V/240 V). What it does (function and performance) Frequency: 433 MHz RF remote control. Receiver: Two independent relays, each with three terminals — Normally Open (NO), Common (COM), Normally Closed (NC). Sensitivity and range: Reception sensitivity >97 dBm; effective control up to 50 meters in open spaces (obstacles will reduce range, but signal can penetrate walls/floors/doors). Operating modes: Momentary, Toggle (factory default), Latched — easy to set or reset depending on the application. Memory: Stores 20 transmitter codes per receiver. A single transmitter can be matched to multiple receivers. Electrical ratings: Relay life >100,000 operations; terminal current capacity 10 A; operating voltage range 85 V–250 V (suitable for 110/120/220/240 V systems). Compatibility and setup Compatible with 433 MHz transmitters that are matched to the receiver. Simple setup and reset: modes selectable by the user; receivers are tested and in toggle mode. Pairing: Matching is required for a transmitter to control a receiver; one receiver can retain up to 20 transmitter codes. Typical applications (practical use cases) Remote lighting control: Switch indoor or outdoor lights (within the voltage/current ratings) from a distance — useful for porches, workshops, or stairwell lighting. Gate, garage, and door control: Operate automatic gates or garage door openers where separate relay outputs are needed for different functions (e.g., open/stop/close wiring). Small appliance or motor control: Control pumps, fans, or other small motors and appliances within the 10 A and 85 V–250 V ratings for automation or convenience. Installation and safety notes Ensure transmitters and receivers are correctly matched before final installation. Verify load current does not exceed the 10 A terminal rating and that devices operate within the 85–250 V range. For permanent installations, follow local electrical codes and consider professional wiring if you are not qualified.
