About this product
A 4-button, 4-channel 433 MHz RF remote control transmitter powered from 12 V. Each button sends its own coded signal to a compatible 433 MHz receiver, so one remote can control up to four separate loads such as relays, gates or lighting circuits. Match the receiver's frequency and encoding before use.
