Difference Between L1 And L2 Light Switch

By | October 20, 2021



Have you ever noticed the difference between an L1 and an L2 light switch? While they look and function similarly, they have key differences that can be important to know when considering which type of switch to use in your home or office. The two major components that differentiate an L1 and L2 light switch are amperage and wattage. In this article, we will dive into the key differentiators between an L1 and L2 light switch so that you can make the best decision for your lighting needs.

Lighting is an important part of any room, whether it’s in a home or an office space. And the type of light switch you choose has a big impact on the overall look and feel of the space. When choosing a light switch, you’ll likely come across two types – an L1 and an L2 switch. While they both look similar, they have some key differences that make them suited for different applications. So, what are the differences between an L1 and an L2 light switch? Let's take a closer look.

The most notable difference between an L1 and an L2 light switch is the amount of amperage and wattage each can handle. An L1 switch typically has a maximum of 15 amps and 1800 watts, while an L2 switch can handle up to 20 amps and 2400 watts. This means that if you’re looking to install lighting for a large space, you will likely need to go with an L2 switch as it can support more power than an L1 switch. Additionally, L2 switches are often used for controlling appliances, such as a dishwasher, that require more power than a standard light fixture.

Another difference between an L1 and an L2 light switch is the wiring. L1 switches are wired in single-pole configurations, meaning they have two wires – one for the hot and one for the load. On the other hand, L2 switches are generally wired in three-pole configurations, which means they have three wires – one for the hot, one for the neutral, and one for the load. This is because L2 switches are designed to handle higher wattage, and thus need more power to function.
