Features:*Very convenient to use, simple wiring diagram connection way. RF Remote Control Switch, can through walls.*Support remote control up to 16 pieces. It can connect to the electronic control lock, intercom doorbell, garage door, light, electric curtain, household appliances, motor control, lifting equipment, security system, etc. So that it can remote unlock the door, close the light, open or close the curtain,etc. *Low power consumption, stable performance. Super small body, occupying less space. *The working mode can be changed by yourself: you can switch to Momentary, Latched dual modes as you need.*Pair with Fixed Code: it can work with any remote control with the same frequency (433MHz 2262 Chip), so you needn't worry about losing remote control any more. (If the remote control is lost, buy one and pair with the PCB board is OK.)Receiver Specifications:Channels: 6Input Power: DC12VStandby Current: ≤10mA Output Current: ≤10A RF Frequency: 433MHzOutput Power: DC/AC OptionalRF working mode: superheterodyne receptionCoded System: Fixed Code (2262 Chip) Decoding mode: 2272 Chip decoding Receive sensitivity: -105dbmRemote control storage: up to 16 PCSWorking mode: Momentary, LatchedWiring type: fixed terminalOutput Terminal: NO , NC , COMReceiver Board Size: Approx. 7 x 5 x 1.8cm / (2.7 x 2 x 0.7”)Fuse Box Size: Approx. 7.5x 5.5 x 2.8cm / (2.9 x 2.2 x 1.1”)  Remote Control Specifications:Frequency: 433MHz  2262 ChipRange: >1000m (open area)Battery: 1*12V 23A (included)Working Current: ≤15mA Shock Resistance: 4.7Quantity: 3PCSRemote Control Size/Per: 10.1 x 3.8 x 1.7cm / (4 x 1.5 x 0.7”)Package Information: Package Size: Approx. 17 * 11 * 3.5cm / 6.7 * 4.3 * 1.4in Package Weight: Approx. 204g / 7.2oz    Package List:1* Receiver Board1* Fuse Box 3* Remote Control
