Key Features

• Wide Voltage Range: Compatible with 5V–24V DC power supplies for maximum flexibility
• 433MHz RF Wireless: Stable radio-frequency communication for responsive, reliable switching
• Single-Channel Relay: Controls one independent circuit — ideal for electric doors, locks, and lighting
• 4 Operating Modes: Point (momentary), Self-locking (toggle), Interlock (A/B switching), and Timed Delay (5s or 10s auto-disconnect)
• Easy Code Copying: Pair with a new remote by following the simple copy steps — compatible with existing 433MHz remotes
• Compact PCB Design: Board size just 3.5 × 3.15 × 1.7 cm — fits neatly into tight enclosures
• ABS Construction: Lightweight and durable housing material
• LED Indicator: Visual confirmation of pairing and relay status at a glance

Operating Modes Explained

1. Point (Momentary): Relay engages while the button is held; releases when button is released. Great for doorbells or brief triggers.
2. Self-Locking (Toggle): Press once to engage the relay; press again to disengage. Perfect for lighting control.
3. Interlock (A/B): Press button A to engage the relay; press button B to disconnect. Ideal for two-action control scenarios.
4. Timed Delay (5s / 10s): Relay automatically disconnects after a 5-second or 10-second delay — great for electric door strikes with auto-release.

Specifications

⚠️ Please Note: Due to customs regulations, this product does not include a battery. Please purchase the required battery separately. Colors may vary slightly from photos due to monitor brightness and lighting settings. Manual measurements may differ by 1–5mm.

How to Pair / Copy Your Remote

Clearing the Remote Code: Press and hold both buttons on the new remote simultaneously until the indicator light flashes continuously, then release — the code is cleared. After clearing, press any key; the light will flash once and go out.

Copying the Code: Hold the original remote in your left hand and the new remote in your right hand, as close together as possible. Hold the desired button on the new remote and simultaneously press the matching button on the original remote. Release when the indicator flashes rapidly — copy successful. Repeat for each button.

Pairing with Control Board: Press the pairing button on the board the appropriate number of times for your desired mode (1x = Point, 2x = Self-lock, 3x = Interlock, 4x = 5s Delay), wait for the LED to stay on, then press the remote button. Continuous flashing confirms successful pairing.

Frequently Asked Questions

Q: What voltage does this wireless relay switch support?

A: This relay switch module supports a wide input voltage range of 5V to 24V DC, making it compatible with a broad variety of power supplies commonly used in home automation and access control projects.

Q: Can I use this relay switch to control an electric door lock?

A: Yes! This 433MHz wireless relay switch is specifically designed for use with electric passage doors, gate openers, and similar access control devices. The timed delay modes (5s or 10s auto-disconnect) make it especially well-suited for electric door strike applications.

Q: Can I copy my existing 433MHz remote to work with this controller?

A: Absolutely. As long as your existing remote operates at 433MHz, you can follow the code-copying procedure outlined in the instructions to clone your original remote's signal to a new remote for use with this controller.

Q: Does the product come with a battery?

A: No — due to customs regulations, a battery is not included with this product. You will need to purchase the appropriate battery separately before use.

Q: How many devices can be controlled with this module?

A: This is a single-channel relay module, meaning it controls one circuit or device at a time. For multi-channel control needs, you would need a multi-channel relay module.
