Harken BRS103/P Switch

HARKEN BRS103/P Switch: Ultimate Control for Your Marine Electrical System

Take command of your vessel´s power with the HARKEN BRS103/P Switch, a premium-grade battery rotary switch engineered for unparalleled safety, reliability, and performance in the demanding marine environment. As a critical component in the Electronics and Electrical Connections category, this switch is designed to provide robust and intuitive management of your onboard battery banks. Whether you are isolating power for maintenance, switching between starting and house batteries, or combining banks for an emergency start, the BRS103/P delivers the confidence and control you need when it matters most.

Key Benefits:

* Uncompromised Safety: The HARKEN BRS103/P is ignition protected, making it safe for installation aboard gasoline-powered boats where fuel vapors may be present. The removable control knob offers an additional layer of security, allowing you to completely isolate the electrical system and prevent unauthorized or accidental activation. This feature is essential for servicing your engine or electrical components with peace of mind.
* Total Power Control: Featuring a clear and decisive 4-position selector (Battery 1 / Battery 2 / Both / Off), this switch provides complete and flexible management of your dual battery setup. Effortlessly switch between independent battery banks to preserve your starting power, or combine the capacity of both batteries in parallel for extra cranking amps or to run heavy loads. The "Off" position provides a single point of disconnection for the entire system.
* Marine-Grade Durability: Built to withstand the harsh realities of saltwater, humidity, and vibration, the BRS103/P is constructed for longevity. The use of tin-plated copper studs and nuts ensures maximum conductivity while offering superior resistance to corrosion, a common point of failure in lesser-quality electrical connections. This robust construction guarantees a reliable power path for years to come.
* Versatile and Tidy Installation: The innovative and patented Contour Locking System allows the switch to be used as a standalone unit or seamlessly locked together with other Harken switches and components. This modular design enables you to create clean, consolidated, and professional-looking battery management clusters. Furthermore, the switch can be either surface mounted or recess mounted for a low-profile, integrated look, while removable side plates provide easy, unobstructed access for routing heavy-gauge battery cables.

Main Features:

* Patented Contour Locking System for modular integration with other Harken products.
* Removable control knob for system isolation and safety lockout.
