2-Channel PWM Relay Switch for RC Car Boat Plane 4.8-10V BEC
2-Channel PWM Relay Switch for RC Car Boat Plane 4.8-10V BEC
2-Channel PWM Relay Switch — Precise Remote Control for RC Models
Take full control of your RC builds with this versatile 2-Channel PWM Electronic Relay Switch. Designed for hobbyists and enthusiasts, this compact module lets you remotely toggle two independent output channels using any standard RC transmitter and receiver. Whether you're firing model rockets, triggering smoke systems, switching navigation lights, or controlling agricultural machinery, this relay switch delivers reliable, responsive performance.
Key Features
- Wide BEC Voltage Compatibility: Operates on 4.8V–10V, supporting standard 5V and high-voltage 7.4V BEC setups. Do not exceed 10V to avoid damage.
- Dual Independent Channels: Independently switch Channel A and Channel B — open, closed, or both open simultaneously for flexible circuit control.
- Standard PWM Signal: Compatible with 1000–2000µs control signals, the same range used by most ESCs and RC receivers.
- High Controlled Voltage Rating: Each output port supports up to 125V maximum controlled voltage, handling a wide range of downstream devices.
- Low Standby Draw: Only ~10mA in standby mode, preserving your battery life during idle periods.
- Compact & Lightweight: Measures approximately 37mm × 26mm × 20mm — easy to mount in tight airframes, hulls, or chassis.
- Configurable Middle Position: Default neutral range of 1300–1700µs for easy integration with your existing RC setup.

Frequently Asked Questions
Q: What RC receivers is this 2-channel PWM relay switch compatible with?
A: This relay switch is compatible with virtually any standard RC receiver that outputs a PWM signal in the 1000–2000µs range, which covers the vast majority of RC car, boat, plane, and rocket receivers on the market today.
Q: Can I use this relay switch with a 7.4V high-voltage BEC system?
A: Yes! This module is specifically designed to support mainstream BEC voltages including standard 5V and high-voltage 7.4V BEC systems. Just ensure the input voltage does not exceed 10V to prevent damage to the module.
Q: What can I connect to the output ports of this relay switch?
A: The output ports support up to 125V maximum controlled voltage, making them suitable for controlling LEDs, lights, smoke generators, launch systems, and other electronic accessories commonly used in RC models.
Q: How do I set the neutral/middle position for my transmitter?
A: The default middle position range is 1300–1700µs. This falls within the standard PWM signal range and should be automatically recognized by most RC transmitters without requiring manual adjustment.
