DC 12V Inline Switch – 25A Waterproof IP67 Inline Power Switch, Heavy Duty DPST Battery Disconnect Switchs with 10AWG Copper Cable for Automotive, Marine, RV & DIY

Description

Product Overview

The Tengsance DC 12V Inline Switch is engineered to meet the demanding requirements of automotive, marine, recreational vehicle, and do‑it‑yourself applications where reliable power management is essential. Built around a robust double‑pole single‑throw (DPST) configuration, the switch can handle up to 25 amps of continuous current while maintaining a stable voltage range of 12 V to 24 V. The inclusion of a 10 AWG copper cable with pre‑installed ring terminals on both ends eliminates the need for additional wiring, allowing installers to connect the switch quickly and securely. The switch housing is molded from high‑grade silicone rubber, providing excellent flexibility, resistance to high temperatures, and superior anti‑corrosion properties that extend the product’s lifespan even in salt‑water or humid environments.

Measuring 1.97 × 1.57 × 4.72 inches and weighing just 2.12 ounces, the unit is compact enough to fit into tight spaces while still offering a prominent, bright‑red waterproof push button. The button’s vivid color not only enhances visibility in low‑light conditions but also gives users an instant visual cue of the switch’s state—red for off and a contrasting color when engaged. The IP67 rating guarantees protection against dust ingress and immersion in water up to 1 meter for 30 minutes, making it an ideal choice for boats, off‑road vehicles, and outdoor equipment that may be exposed to rain, splashes, or accidental submersion.

Usage

Designed with versatility in mind, this inline switch excels in a wide range of real‑world scenarios. In automotive settings, it can be used to isolate battery circuits, control auxiliary lighting, or manage power to aftermarket accessories such as winches, compressors, and high‑draw devices. Marine enthusiasts will appreciate the switch’s ability to safely disconnect shore power or onboard batteries, protecting sensitive electronics from voltage spikes caused by wave action or faulty wiring. For recreational vehicle owners, the switch offers a convenient method to shut off power to interior lighting, water pumps, or entertainment systems when the vehicle is parked, conserving battery life and enhancing safety.

DIY hobbyists and makers will find the switch particularly useful in solar power projects, where it can serve as a manual disconnect for charge controllers, inverters, or battery banks. Its 30 cm (approximately 12 inch) cable length on each side provides enough reach to route the switch to a convenient location without creating excess slack that could interfere with other components. The pre‑installed ring terminals simplify the installation process, allowing users to secure the switch with a single nut on each side, reducing the risk of loose connections that could lead to arcing or overheating.

Because the switch is rated for both 12 V and 24 V systems, it can be deployed across a spectrum of equipment, from small‑scale motorcycle electrical systems to larger industrial control panels that require a reliable, weather‑proof disconnect. Whether you are installing the switch in a custom‑built electric bike, a portable generator enclosure, or a remote weather station, the combination of high current capacity, waterproof protection, and user‑friendly design ensures dependable operation under the toughest conditions.

FAQ

What voltage range does the switch support?

The switch is designed to operate safely within a 12 V to 24 V DC range, making it compatible with most automotive, marine, and solar power systems.

Can the switch be used in a wet environment?

Yes, the switch carries an IP67 rating, which means it is fully protected against dust ingress and can be submerged in up to 1 meter of water for 30 minutes without damage.

Is the included cable length sufficient for most installations?

The product comes with a 30 cm (approximately 12 inch) cable on each side, providing enough reach for typical mounting locations while keeping excess slack to a minimum.

What does DPST mean and why is it important?

DPST stands for Double‑Pole Single‑Throw. It means the switch can disconnect two conductors simultaneously, offering a safer way to isolate power compared to single‑pole switches.

How does the warranty work?

Tengsance offers a standard warranty that covers any manufacturing defects. If the switch fails under normal use within the warranty period, you can contact our support team for a replacement or repair.
