The 4 Channel Wireless Four Button RF Remote without Control Transceiver Module is a compact and easy-to-use solution for wireless control applications. Designed for basic remote switching needs, this module features Non-Locking (Momentary) mode, where each button press results in a short high-level output signal from the receiver, returning to low once the button is released. RF Remote  is ideal for hobby electronics, DIY automation projects, and prototyping, the remote control works with standard 315 MHz ASK-type RF receivers and decoders (not included in this package). This transmitter is commonly used in systems like wireless door locks, remote lighting, garage doors, and microcontroller-based applications. Note:
The remote control does not come with the battery due to Air shipping limitations you have to buy it separately.
Ensure the receiver is compatible with 315 MHz ASK signals and fixed code encoding.

Operation Modes (This Unit: Non-Locking by Default):
Non-Locking (Jog Mode):

Output is high only while a button is pressed.

Once released, output returns to low.

Ideal for momentary control such as door locks, relays, or MCU triggers.

Self-Locking Mode (Not pre-configured):

Pressing a button toggles the output ON; pressing again turns it OFF.

Useful for devices like lights or motors that need to remain active.

Interlocking Mode (Not pre-configured):

Only one output can be active at a time.

Activating one channel deactivates the others.

Suitable for fan speed control, multi-state switches, etc

Note: Only Non-Locking mode is enabled by default. Reconfiguration is required for Self-Locking or Interlocking modes.
