DC 12V 4CH Channel 433Mhz Wireless RF Switch Long Range Wireless Remote Control Switch DC12V RF Relay Receiver Module Transmitter Toggle Switch 1527 Chip Smart

​Features: *Very convenient to use, simple wiring diagram connection way.  *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, etc. So that it can remote unlock the door, close the light, open or close the curtain,etc.  *The Remote Control four buttons could respectively copy four different types of chips, that is a remote control can operate four different types of facilities.  *The working mode can be changed by yourself: you can switch to momentary, toggle, latching three modes as you need. *Learning pair code: it can work with any remote control with the same frequency, 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.)
