DC12V 433MHz Remote Control Kit

This kit provides a transmitter and receiver module operating at 433MHz for 12V DC automation tasks. It includes a single relay switch suitable for basic on-off control of compatible devices. The set targets hobbyists and installers building simple wireless switching projects.

Bundled Transmitter and Receiver

The paired transmitter and receiver arrive pre-configured to work together without additional coding. The single relay output changes state when the remote button is pressed, enabling direct load switching. Users needing multiple independent channels or voltage-free contacts will require a different module.

Questions about this item

Will the relay contacts need replacement after many switching cycles?

The module uses a single electromechanical relay; its contacts will eventually wear after repeated switching operations.

What limits continuous operation when the transmitter runs on 12 V?

Sustained transmission at 433 MHz is limited by the module's duty-cycle rating and heat dissipation in the RF stage.
