PWM RC Electronic Switch 2-20A 3-30V for Drone & Water Pump

PWM Signal Electronic Switch – RC Drone & Water Pump Controller

Take precise command of your RC drone accessories, water pumps, aerial models, and more with this versatile PWM Signal Electronic Switch. Available in both low-voltage (2A / 3–5V) and high-voltage (20A / 3–30V) versions, this compact controller lets you toggle devices on and off directly from your remote control's 2-position channel — no extra wiring or complex setup required.

Key Features

• Wide Voltage Range: Low voltage version: 3.0V–5V | High voltage version: 3.0V–30V
• High Current Capacity: 2A (low voltage) / 20A (high voltage) output
• PWM Signal Control: Below 1.5ms = OFF, above 1.5ms = ON — simple and reliable switching
• Built-in Status LED: Slow flashing = no output; long/steady flash = output active — always know your switch state at a glance
• Lightweight Design: Just 3g (low voltage) or 5g (high voltage) — barely adds any weight to your build
• Silicone Construction: Durable and heat-resistant material for long-lasting performance
• 2-Channel Remote Operation: Controlled via a standard 2-level RC remote channel — compatible with most RC transmitters
• Versatile Applications: Ideal for RC drones, aerial photography rigs, water pumps, lights, servos, and other RC-operated accessories

Frequently Asked Questions

Q: What devices can I control with this PWM signal electronic switch?

A: This RC PWM electronic switch is compatible with a wide range of 12V/24V/5V accessories including water pumps, LED lights, sprayers, servos, and other drone or aerial model peripherals. As long as your device operates within the voltage and current rating of the selected version, it can be switched via your RC remote.

Q: How do I know which version — low voltage or high voltage — to choose?

A: Choose the low voltage version (2A / 3–5V) for small, low-power accessories typically found on micro drones or 5V-powered devices. Choose the high voltage version (20A / 3–30V) for larger pumps, high-current motors, or applications requiring more power, such as agricultural drones or heavy-duty RC models.

Q: How does the LED indicator work on this RC switch?

A: The built-in status LED provides a clear visual cue: a slow flashing LED means there is currently no output (switch is OFF), while a long or steady flash means the switch is active and output is live (switch is ON). This makes it easy to confirm your switch state without a multimeter.

Q: Is this switch compatible with my RC transmitter?

A: This switch is designed to work with standard 2-level RC remote control channels that output a PWM signal. Most hobby-grade RC transmitters and receivers output a standard PWM signal, making this switch broadly compatible. Simply assign a 2-position switch channel on your transmitter to toggle it on and off.
