The 433MHz Single-Channel Wireless RF Remote Control Switch Module is a complete remote control solution designed for applications requiring simple, reliable wireless switching. It consists of a transmitter (remote control) and a receiver (with relay output). No programming or complex wiring is needed — it works out of the box to wirelessly control lights, motors, pumps, and other equipment.

The receiver uses a superheterodyne receiving architecture, providing excellent anti-interference capability and stable signal reception. It supports a wide AC 85–220V input voltage, allowing direct connection to household or industrial AC power without an additional transformer or power adapter. The built-in 10A high-power relay can handle loads up to 250VAC / 30VDC, sufficient to drive most home appliances and small-to-medium motor equipment.

The module uses intelligent learning code technology and supports common fixed-code and EV1527 learning-code remotes. With the onboard learning button, you can pair a remote in seconds without any professional tools. The receiver can store up to 32 different remote controls, convenient for multiple family members or managers.

The module offers three switchable working modes, selected by the number of short presses on the learning button: Jog mode (relay closes while the remote button is held, opens when released), Toggle mode (press once to turn on, press again to turn off), and Latch mode (requires two remote buttons, one for on and one for off). This flexibility allows it to adapt to scenarios ranging from access control to lighting management.

The included transmitter (remote control) operates at 433MHz and uses a 23A 12V battery (battery included in some versions). The 433MHz band is widely used in Europe and many other regions, offering a good balance of range, penetration, and antenna efficiency. Effective remote distance reaches up to 100 meters in open areas and approximately 20–50 meters indoors through walls. Signals can penetrate walls, floors, and doors, letting you control devices reliably from anywhere in your home.

The receiver features a compact PCB design with a plastic enclosure, making it easy to install in distribution boxes, light fixtures, or equipment interiors. The fixed screw terminals accept bare wires directly and tighten securely for simple installation.

Whether you are a homeowner automating lighting, an installer building access control systems, or a business purchasing in bulk for smart home or industrial projects, the 433MHz RF Remote Control Switch Module offers a reliable, cost-effective solution.

Usage

First-Time Setup and Pairing

  1. Clear factory codes (recommended for first use) — After powering the receiver, long-press the learning button for about 8 seconds until the LED indicator lights up, indicating all stored remote codes have been cleared.

  2. Enter learning state — Short-press the learning button once. The LED indicator turns off, indicating the receiver is in learning mode.

  3. Select working mode — In learning state, short-press the learning button 1 time for Jog mode, 2 times for Toggle mode, or 3 times for Latch mode. The number of LED flashes corresponds to the selected mode.

  4. Pair the remote — In learning state, press any button on the remote. The LED indicator flashes 3–5 times and then turns off, indicating successful learning.

  5. Latch mode pairing — In Latch mode, two buttons must be learned: first press the remote’s “A” button (automatically assigned as “On”), then press the “B” button (automatically assigned as “Off”).

Working Mode Descriptions

Mode Operation Remote Buttons Required
Jog Relay closes while button is held; opens when released 1 button
Toggle Press once to turn on, press again to turn off 1 button
Latch Press A to turn on, press B to turn off 2 buttons

Wiring Instructions

  1. Receiver power — Connect AC 85–220V to the receiver’s power input terminals.

  2. Load wiring — Connect the device to be controlled (light, motor, etc.) to the relay’s normally-open (NO) or normally-closed (NC) contacts.

  3. Power-on test — After powering on, the LED indicator should light up. Press the remote button; the relay should click and switch state.

Typical Applications

  • Home lighting control — Remote switching of lamps, ceiling lights, and LED strips

  • Electric doors and access control — Remote control of electric doors, rolling shutters, and garage doors

  • Motor and pump control — Remote start/stop of small motors, pumps, and fans

  • Security systems — Arm/disarm integration with alarm systems remotely

  • Industrial equipment control — Simple remote switching of commercial and industrial electrical equipment

Notes for Business Buyers

  • Three working modes — One module adapts to multiple control requirements, reducing inventory SKUs

  • Suitable for bulk purchasing — Ideal for smart home, security engineering, teaching experiments, and product development

Q: What is the 433MHz RF Remote Control Switch Module used for?

It is a complete wireless remote control solution for switching lights, motors, pumps, and other equipment. It consists of a transmitter (remote) and a receiver with a relay output.

Q: What is the difference between the 315MHz and 433MHz versions?

Both operate similarly, but use different frequency bands. 433MHz is widely used in Europe and many other regions, offering a good balance of range and penetration. 315MHz is more common in North America and some Asian markets. Choose the frequency that complies with your region’s regulations.

Q: How do I pair the remote with the receiver?

Short-press the learning button once (LED turns off), then press any button on the remote. The LED flashes 3–5 times and then turns off, indicating successful pairing.

Q: What is the difference between the three working modes?

Jog: relay closes while the remote button is held, opens when released. Toggle: press once to turn on, press again to turn off. Latch: requires two remote buttons, one for on and one for off.

Q: How many remotes can the receiver store?

It can store up to 32 remote controls, convenient for multiple users.

Q: What is the remote control distance?

Approximately 100 meters in open areas, and about 20–50 meters indoors through walls. Actual distance is affected by wall material, electromagnetic interference, and other factors.

Q: How do I clear all learned remote codes?

Long-press the learning button for about 8 seconds until the LED indicator lights up, then release. All codes are cleared.

Q: What is the difference between the receiver's operating voltage and the load voltage?

The receiver requires AC 85–220V for power. The relay’s load contacts can independently control AC or DC devices (up to 10A), regardless of the receiver’s supply voltage.

Q: How much power can this module control?

The relay is rated for 10A. For AC resistive loads, it can control up to approximately 2200W (such as lighting). For inductive loads like motors, keep load current below 60–70% of the rated value.

Q: Can I purchase in bulk for engineering projects?

Yes. This module is suitable for both individual users and business purchasing, including smart home installation, security engineering, teaching experiments, and product development.
