PWM Electronic Switch 2A/20A Remote Control Motor Controller
PWM Electronic Switch 2A/20A Remote Control Motor Controller
PWM Signal Electronic Switch Controller — 2A & 20A Versions
Take precise remote control of your motors, model airplanes, water pumps, and more with this compact PWM Signal Electronic Switch Controller. Available in a low-voltage 2A version (3V–5V) and a high-current 20A version (3V–30V), this versatile module lets you toggle power on and off via a standard 2-segment RC remote switch — no rewiring required.
Whether you're building a DIY robotics project, controlling a DC water pump, or integrating into an RC aircraft setup, this controller offers a clean, reliable switching solution with a built-in LED status indicator so you always know the output state at a glance.
Key Features
- Dual versions: 2A output (3V–5V operating) & 20A output (3V–30V operating)
- PWM signal control: Pulse width below 1.5ms = OFF; above 1.5ms = ON
- LED work indicator: Slow blinking = no output; solid on = active output
- 2-segment remote switch compatible — easy plug-and-play integration with RC receivers
- Wide application: Motors, model airplanes, DC water pumps, fans, lights, and more
- Compact plastic housing — lightweight and easy to mount in tight spaces
- Low-voltage EU LVD compliant: Below 50VAC or 75VDC

Frequently Asked Questions
Q: What is the difference between the 2A and 20A versions of this PWM electronic switch?
A: The 2A (low-voltage) version operates on 3V–5V and is suited for small DC motors and low-power devices. The 20A (high-current) version operates on 3V–30V and handles heavier loads such as high-power water pumps, larger motors, and high-current applications in robotics or RC builds.
Q: How does the PWM signal control the switch?
A: The controller reads the pulse width from a standard RC receiver signal. A pulse width shorter than 1.5ms keeps the switch in the OFF state, while a pulse width longer than 1.5ms activates the switch to the ON state — making it fully compatible with standard 2-segment RC remote controls.
Q: What does the LED indicator on this electronic switch tell me?
A: The onboard LED provides a quick visual status check. A slowly blinking LED means there is no output (switch is off), while a continuously lit (solid) LED means the switch is active and output is being delivered to your connected device.
Q: Can I use this controller with a model airplane receiver?
A: Yes. This PWM switch controller is designed to work directly with standard RC model airplane receivers using the 2-segment switch channel output, making it a popular choice for triggering accessories like lights, pumps, or secondary motors on RC aircraft and vehicles.
