AC Socket Types Explained: The Ultimate Guide to Choosing the Right AC Socket with FILN
Let’s be honest—AC Sockets probably aren’t the first thing that comes to mind when you think of electrical components. But try running any appliance or tool without one, and suddenly they become essential. AC Sockets play a critical role in safely delivering alternating current (AC) power to devices across industries.
So, what makes one AC socket different from another? That’s where this guide comes in. Whether you’re a manufacturer, engineer, or DIY enthusiast, understanding the different AC socket types can help you make better, safer choices.
And when you’re ready to purchase? FILN, a trusted name in electrical components, has every type of AC Socket you’ll need.
What is an AC Socket?
An AC Socket, or AC Power Socket, is a connector that allows electrical appliances to be powered by alternating current (AC) from a power source. You’ll find AC sockets in just about everything—from household electronics to industrial machinery. With electricity being the lifeline of any device, choosing the right AC socket isn’t just a matter of convenience—it’s a matter of safety, reliability, and performance.
Why Choosing the Right AC Socket Matters
Not all AC Sockets are created equal. Some are designed for high-voltage equipment, while others are better suited for compact electronics. Choosing the right one affects:
-
Electrical safety
-
Device longevity
-
Operational efficiency
Overview of the 3 Main AC Socket Types
AC Sockets vary in complexity and capability. Here are the three main types:
-
Basic AC Socket – No fuse, no switch
-
AC Socket with Fuse – Added protection
-
AC Socket with Fuse and KCD Rocker Switch – Full control & safety
Let’s explore each in detail.

Type 1 – Basic AC Socket (Without Fuse & Switch)
Key Features
-
Pure socket design

Minimal components
-
Cost-effective
Common Applications
-
Home electronics
-
Basic industrial devices
-
Consumer-grade equipment
Pros and Cons
Pros:
-
Affordable
-
Easy to install
-
Minimal footprint
Cons:
-
No built-in protection
-
Less suitable for sensitive or high-power devices
When to Choose This Type
Opt for this if your device already has internal protection or you’re looking to keep things simple and budget-friendly.

Type 2 – AC Socket with Fuse
Key Features
-
Integrated fuse for circuit protection
-
Slightly larger form factor
