Wireless 433 MHz Switch
This 433 MHz wireless remote control switch operates on a 12 V DC supply and uses a single-channel relay with a learning-code receiver. The compact plastic module measures 60 by 36 by 12 mm and pairs with an included transmitter for radio-frequency control up to 150 metres.
Gate and alarm installers
The switch suits installers adding wireless triggers to electric telescopic doors, road gates or alarm systems where a single 12 V circuit must be toggled remotely. It does not serve buyers who need multi-channel switching, higher voltage contacts or a mains-rated enclosure for direct 220 V loads.
433 MHz learning-code link
The defining specification is the 433 MHz learning-code RF link that pairs one transmitter with one receiver module. If the project requires a different frequency, multiple independent channels or a pre-paired fixed code, this unit will not match the requirement.

Questions about this item
Should I choose the 12 V or 220 V version of this remote switch?
The receiver runs on 12 V DC while the included transmitter uses a 220 V supply, so you need a 12 V source for the relay module.
What does the 433 MHz frequency mean for range inside a building?
The 433 MHz signal typically reaches 50 to 150 metres in open air; walls and metal structures will reduce the practical distance.
How does the single‑channel 433 MHz RF link limit what I can control?
One channel operates one relay, so each receiver controls only a single 12 V circuit; add more receivers for additional circuits.
