Outdoor Extension Cord with Waterproof Switch

This 1.5 ft outdoor extension cord includes an inline waterproof on/off switch for convenient control of connected devices. It is built with 14 AWG SJTW wire rated for 15A at 125V and 1875W. The UL certified design suits outdoor lighting, holiday displays, pumps and patio equipment.

Check Your Power Requirements

Verify that your intended load does not exceed the 15A and 1875W ratings at 125V. The cord uses NEMA 5-15P and NEMA 5-15R connectors, so ensure your outlets and plugs match this standard three-prong configuration. Note the switch is water-resistant, not submersible, and the supplier suggests a separate weatherproof cover for connection points.

Durable Vinyl Sheath and Inline Switch

The flexible vinyl cord sheath and durable plug housing are designed for long-term outdoor use. The integrated waterproof switch allows one-key operation without unplugging devices in wet conditions. At 1.5 ft, the short length is intended for extending a switched connection near an outlet rather than spanning long distances.

Questions about this item

What comes in the box and do I need to buy anything else for outdoor use?

The box contains the 1.5 ft 14 AWG SJTW extension cord with a built-in waterproof on/off switch and NEMA 5-15P to NEMA 5-15R connectors. For permanent outdoor installations the manufacturer recommends adding a separate outdoor plug cover to protect the connections from rain, snow and dust.

Which version of this cord should I choose for 15 A loads?

This single model is rated 15 A at 125 V (1875 W) and uses 14 AWG SJTW wire, so it covers the full 15 A capacity without needing a heavier-gauge variant.

What does the 1875 W rating mean when I plug in my holiday lights?

It is the maximum continuous power the cord can deliver at 125 V; as long as the total draw of your lights, pump or fountain stays at or below 1875 W the switch and wiring will operate within their UL-listed limits.
