PWM Electronic Switch Module 2A 20A 30A RC Model Electronic Switch 3‑30V PWM Signal Controlled Power Switch For RC Airplane Drone DIY Modification Project

RC PWM Electronic Switch 2A /20A /30A

📌 Product Overview

This RC PWM electronic switch is designed for radio‑controlled model applications, it realizes power on/off control by receiving PWM signal from RC transmitter receiver. There are three optional versions: low‑voltage 2A, high‑voltage 20A and high‑power 30A. No extra relay needed, support large‑current load switching, compact size, easy wiring with JST & JR connectors. Users can control connected equipment via 2‑position switch on remote controller. PWM signal rule: low position 1‑1.5ms = power off; high position 1.5‑2.0ms = power on. Built‑in LED indicator for working status feedback.

✨ Key Features

✅ Controlled by standard RC PWM signal, compatible with most RC receivers ✅ Multiple specification options: 2A / 20A / 30A for different load demands ✅ Output voltage is consistent with input voltage, no voltage conversion ✅ LED status indicator: slow flashing = off without output; steady on = output powered ✅ Plug‑and‑play with JST power connector and JR signal connector ✅ Small lightweight structure, convenient for installation inside RC models

⚠ Important Usage Notice

1. Please do not exceed the rated maximum current, over‑current will cause wire heating or permanent burnout of the electronic switch.
2. Suggest to use two‑stage remote switch control mode. LED will light up when switch is at ON position.
3. Output voltage equals input voltage, it cannot realize voltage boost or reduction.
4. Kind reminder: If there are version differences or images not been updated, please refer to the actual product. Thank you!

🛠 Application Scenarios

Ideal for RC drone lights, RC car lights, model auxiliary equipment power switching, remote‑controlled on‑off of model‑borne loads, various DIY remote power control projects.
