5V Relay 5 Pin Songle is a reliable electromagnetic relay designed to switch AC or DC loads safely using a low-voltage 5V DC control signal. When the relay coil is energized, the internal contacts change state, allowing isolation between the low-voltage control circuit and high-power load circuit.
This relay features 5 pins, including coil terminals and COM, NO (Normally Open), and NC (Normally Closed) contacts, offering flexible switching options. It is commonly interfaced with Arduino, ESP8266, ESP32, and other microcontrollers using a transistor or relay driver circuit.
The Songle 5V relay is widely used in home automation systems, smart switches, motor control, lighting control, and power switching applications. Its compact design, stable performance, and high reliability make it suitable for students, hobbyists, and professionals working on automation and control electronics projects.
