3 Pin DC Power Jack

A 3-pin DC power jack is a commonly used connector type designed to handle direct current (DC) power delivery with added stability and reliability. These connectors are widely favored in electronics and industrial applications, thanks to their ability to offer improved grounding, enhanced safety features, and multiple pin configurations to support various power needs. Their robust design and secure fit make them ideal for devices where stable, uninterrupted power is essential.

A 3-pin DC power jack has a unique structure that includes three connection points:

1. Positive Pin – Typically delivers the positive voltage needed to power the device.

2. Negative Pin – The ground connection that completes the circuit.

3. Switching Pin – The third pin serves as a switching mechanism. It is often used to cut off battery power when an external power source is connected or to allow alternative power sources to engage.

In laptops, cameras, and handheld devices, the 3-pin design is used to seamlessly switch between battery and AC power. The switching pin ensures that as soon as external power is connected, the battery is disengaged, preserving its lifespan.

A DC jack is a type of electrical connector that is used to power electronic devices. It is typically comprised of a cylindrical barrel that contains a center pin, and is often used to connect devices such as laptops, routers, and similar electronics to a power source such as an AC adapter or battery pack.The housing of the Power Jack is made of Plastic and the jack is provided for P.C.B. mounting.  DC Power Jack with solder Pins for PCB mounting suitable for models.
