What Are Modular Switches? A Complete Beginner’s Guide
If you’re building a new home or renovating an old one, you’ve probably heard the term modular switches. But what exactly are they? Are they better than the traditional ones? In this guide, we’ll walk you through everything you need to know about switches in simple, easy-to-understand language.
🔌 What Are Modular Switches?
A modular switch is a type of electrical switch that allows flexibility in design and functionality. Unlike the old-school traditional switches that come in fixed layouts, electrical switches can be customized and easily installed, just like how you can plug different parts into a LEGO block.
They are:
- Modern in design
- Safe to use
- Easy to maintain or replace
✅ Think of them as upgraded versions of traditional switches, designed to look good and work smart.
⚙️ How Do Modular Light Switches Work?
Light switches operate on the same basic principle as traditional light switches — they complete or break an electrical circuit. But the design makes a big difference:
No exposed wiring: Everything stays neat and safe.
Snap-in modules: You can add or remove switch units easily.
Independent function units: Like a fan regulator, USB charger, or night lamp — all in the same switchboard.
