Understanding Light Switch Replacement
Light switches are essential components of your electrical system and are used daily. Over time, they may wear out, become outdated, or need an upgrade to a smart or dimmer switch. Replacing a light switch involves more than swapping out old for new—it also includes verifying wiring compatibility, ensuring safety, and considering the aesthetics of your space.
Key Considerations:
Safety First: Always turn off power at the breaker box and use a voltage tester to confirm no live current.
Switch Type: Determine whether you need a single-pole, three-way, dimmer, or smart switch based on the location and function.
Aesthetics: Consider the design (toggle, rocker, or decorative) and finish to complement your decor.
