Can a Waterproof Light Switch Be Installed Outdoors?

If you're installing a new light switch outdoors, the most important consideration is protecting electrical connections from moisture and corrosion. That's why it's crucial to use a waterproof light switch box when running wiring in wet or damp locations. These specially designed enclosures house electrical switches, outlets and junctions and are available in a variety of sizes to suit any outdoor wiring project.

Choose a weatherproof switch box that's designed for the specific type of outdoor lighting system you're connecting. There are single-gang options to control a light, and double-gang and 3-way versions to control multiple lights or other outdoor devices. They're available in various colors to match your light fixture or the surrounding landscape.
You'll also need a waterproof switch cover. These covers completely encase the switch, so you don't have to open a flip lid or protruding toggle to access the switch. Some have a hinged flap that opens to reveal the light switch, while others have an external lever to engage it.
