## **SPDT 5V Relay Module – 5-Pin PCB Mount Type**

The **SPDT 5V PCB Mount Relay (Single Pole Double Throw)** is an **electromechanical
switch** that allows low-power digital circuits like microcontrollers to control
high-voltage AC or DC devices. Operating at just **5V DC**, this relay is widely
used in **automation**, **home appliances**, **IoT projects**, **robotics**, and**
switching applications**.

The **5-pin design** makes it easy to mount directly onto a PCB, and the **SPDT 
configuration** means it has one common terminal that can be connected to either
of two outputs (Normally Open or Normally Closed), offering **flexible switching
options**.
