5V 7A DC Mini Power Relay – SPDT (Single Pole Double Throw)

The 5V 7A Mini Power Relay is a compact and highly efficient SPDT (Single Pole Double Throw) relay designed for controlling high-current AC/DC appliances. It enables low-power microcontrollers or sensor outputs to switch high-power loads safely and efficiently.

Key Features

✔ Reliable Switching – Controls AC loads up to 250V and DC loads up to 30V
✔ Compact Sugar Cube Design – Ideal for PCB mounting in space-constrained applications
✔ High Current Capacity – Rated for 7A switching, suitable for high-power devices
✔ SPDT Configuration – Provides NO (Normally Open) and NC (Normally Closed) contacts for flexible operation
✔ Low Trigger Voltage (5V DC) – Easily activated by microcontrollers (Arduino, ESP32, STM32, Raspberry Pi, etc.)
✔ Wide Application – Used in home automation, security systems, industrial control, and IoT projects

Wiring Guide

1️⃣ Coil End 1 & Coil End 2 – Connect to 5V DC power source (one end to +5V, the other to GND)
2️⃣ COM (Common) – Connect to one end of the load
3️⃣ NC (Normally Closed) – Connect to the other end of the load if you want it ON by default
4️⃣ NO (Normally Open) – Connect to the other end of the load if you want it OFF by default

💡 Example Usage: Control lights, fans, motors, solenoids, security systems, or automation circuits using a microcontroller.

Package Includes:

✔ 1 x 5V 7A Mini Power Relay (SPDT)
