2-Channel RC Relay Switch | 3-Mode PWM Controller 10A
2-Channel RC Relay Electronic Switch – 3 Working Modes PWM Controller
Take precise control of your RC projects with this versatile 2-Channel RC Relay Electronic Switch. Designed for RC receiver integration, this compact PWM controller supports three distinct operating modes and handles serious switching loads — making it ideal for hobbyists, makers, and RC enthusiasts who need reliable, programmable relay switching.
Key Features
- 3 Selectable Working Modes for flexible circuit control:
- Mode 1: Both channels open and close simultaneously.
- Mode 2: One channel opens while the other closes; both can also close simultaneously.
- Mode 3: Flash mode — 1-second interval switching; one channel opens while the other closes, with simultaneous close option.
- Wide PWM Signal Compatibility: Accepts 3–5V high-level PWM pulse-width signals in the 900–2100µs range — compatible with most standard RC receivers.
- High Switching Capacity: Rated at 10A / 30VDC and 10A / 250VAC for robust load switching.
- Receiver Power Supply: 4.8–8.4VDC input — works seamlessly with standard RC battery packs.
- Low Voltage Safe: EU LVD compliant — operates below 50VAC or 75VDC signal thresholds.
- Compact & Easy to Install: Plug directly into your RC receiver channel for instant relay control.

Frequently Asked Questions
Q: What RC receivers is this 2-channel relay switch compatible with?
A: This RC relay switch is compatible with most standard RC receivers that output a PWM signal between 900–2100µs at 3–5V high-level logic. This covers the vast majority of common RC transmitter/receiver systems used in hobby cars, boats, planes, and DIY builds.
Q: Can I use this relay switch to control both AC and DC loads?
A: Yes. The relay terminals are rated for 10A at 30VDC and 10A at 250VAC, so it can switch both DC accessories (lights, motors, servos) and AC loads within those ratings. Always ensure your load does not exceed the rated current and voltage limits.
Q: How do I select between the 3 working modes?
A: The working mode is selected via the onboard mode selector on the relay switch. Mode 1 operates both channels simultaneously, Mode 2 operates channels alternately with an option for simultaneous close, and Mode 3 adds a 1-second flash interval to the alternating operation. Refer to the included instructions for exact mode-selection steps.
Q: What power supply does the RC relay switch require?
A: The receiver side of this switch requires a power supply of 4.8–8.4VDC, which is standard for most RC battery packs including 2S LiPo and standard NiMH packs used in RC hobby applications.
