433MHz Wireless Remote Control Switch AC/DC 30A Relay – 100M Range

Control Any Load Wirelessly — Up to 100 Metres Away

The 433MHz Wireless Remote Control Switch gives you effortless on/off control of water pumps, motors, LED lighting, garage doors, and more — all from up to 100 metres (open field) without running a single extra wire. Whether you're running on AC mains (75–240 V) or a DC system (9–72 V), this compact relay receiver handles both, making it one of the most versatile wireless switches available.

Made in Mainland China.

Frequently Asked Questions

Q: What is the maximum continuous load current for this 433MHz wireless relay switch?

A: Although the relay is labelled 30A, the rated continuous load current is 15A (at both 110 VAC and 240 VAC). The 30A figure refers to the allowable peak inrush current only. Always ensure your load's continuous draw stays below 15A to protect the relay and your equipment.

Q: Can I use this wireless remote switch with DC systems like solar setups or 12V batteries?

A: Yes — the receiver board accepts both AC 75–240 V and DC 9–72 V, making it fully compatible with 12V, 24V, 48V, and 72V DC systems such as solar installations, battery banks, and automotive or marine applications.

Q: How do I pair additional remote controls with the 433MHz receiver?

A: The receiver uses a learning code system, so you can pair multiple transmitters. Simply select your desired mode by pressing the Learning button the appropriate number of times, wait for the LED flash confirmation, then press the new transmitter button — the LED will flash 3 times to confirm successful pairing. The receiver also accepts 315 MHz remote controllers for extra flexibility.

Q: What operating modes are available on this wireless relay switch?

A: There are 6 operating modes: Momentary (relay activates only while button is held), Toggle (button alternates relay on and off), Latched (relay stays on until commanded off), and three automatic Delay-OFF modes that cut power after 5, 10, or 15 seconds respectively.
