Blue Sea Systems®, a leading provider of high-quality marine electrical components known for safety, reliability, and performance, has announced the Blue Sea MiniSwitch™, a compact, marine-grade, terminal-mounted disconnect switch engineered to safely isolate power, prevent battery drain, and simplify installation for boaters, RV owners, and off-grid users.

“Battery isolation is one of the most important yet overlooked aspects of electrical system safety and battery health,” said Ton De Winer, President, Power Solutions for Navico Group. “The MiniSwitch was designed to make that protection simple and accessible. Its enclosed, marine-grade construction eliminates exposed live components, while the compact, terminal-mounted design provides a convenient way to disconnect power and protect batteries from unnecessary drain during storage.”

Designed with safety at its core, the MiniSwitch features a fully enclosed housing that covers live electrical components, helping reduce the risk of accidental short circuits and sparks. The rugged construction utilizes UV-stabilized, corrosion-resistant materials engineered to withstand harsh marine and outdoor environments, including prolonged sun exposure, vibration, and saltwater conditions.

Despite its compact footprint, the MiniSwitch is built to handle heavy electrical demands, carrying continuous high amperage without overheating or dropping voltage. It keeps high-draw electronics running smoothly while protecting the battery setup from thermal damage under peak loads.

The MiniSwitch mounts directly to the battery terminal, eliminating the need for additional wiring or complex modifications. With a simple turn of the switch, users can quickly disconnect power, preventing battery drain during storage and helping extend battery life.

Combining safety, durability, and ease of installation, the Blue Sea MiniSwitch delivers a practical solution for reliable battery protection wherever power systems are deployed.
