Rich Solar RS-BS275 275A On/Off Battery Switch
The Rich Solar RS-BS275 275A On/Off Battery Switch is built for safe battery isolation in RVs, vans, boats, trailers, solar battery systems, inverter setups, and other DC power applications. With a removable ergonomic knob, glass-fiber reinforced nylon enclosure, flexible surface or panel mounting, removable wiring windows, and a 275A continuous DC rating, this switch gives customers a clean way to disconnect battery power when servicing, storing, or protecting a DC electrical system.
Product Overview
The RS-BS275 is designed to help customers safely shut off battery power when a DC system is not in use, during maintenance, or when equipment needs to be isolated. It is a practical add-on for battery banks, inverter systems, RV power builds, marine wiring, off-grid solar systems, and backup power setups.
The red on/off knob gives users a clear physical disconnect point, while the removable knob design can help prevent unauthorized or accidental use when isolation is needed.
Built for Safer Battery Isolation
A battery switch gives customers a simple manual disconnect point between the battery bank and connected DC equipment. That matters for servicing, storage, troubleshooting, transport, emergency shutoff planning, and preventing unnecessary parasitic draw when the system is not being used.
Key Features That Matter
This description keeps the focus on the real buying decision: current rating, removable isolation knob, mounting flexibility, wiring access, enclosure durability, ignition protection, and terminal compatibility.
The ergonomic red knob is designed for easy on/off control and can be removed for isolation and safety. That helps prevent accidental switching or use when the battery system should remain disconnected.
The robust glass-fiber reinforced nylon enclosure is built for demanding DC electrical environments where the switch may be mounted near batteries, inverters, solar equipment, or vehicle power systems.
Removable windows help provide unobstructed wiring access, making it easier to route battery and inverter cables into the switch enclosure during installation.
The switch uses M10 / 3/8" terminal studs, giving customers a clear connection point for properly sized battery cables, lugs, and DC wiring hardware.
Surface or Panel Mount Flexibility
The RS-BS275 can be installed using surface or panel mount options, giving customers more flexibility when planning battery compartments, inverter bays, marine electrical panels, RV storage areas, and off-grid power rooms.
That mounting flexibility makes it easier to place the switch where it can be reached quickly while still keeping cable routing clean and protected.
