The BEP Dual Operation VSS Switch HD Optic is a high-current, marine-grade battery switch built for demanding 12V and 24V electrical systems. Rated for up to 500A continuous, this switch gives you safe, reliable control of battery banks on boats, RVs, and off-grid setups—perfect for managing house and start batteries with confidence.
This VSS (Voltage Sensitive Switch) design allows easy manual switching while supporting secure operation options for lockout or remote actuation (model-dependent configuration). It’s ideal for installations where safety, convenience, and quick isolation are critical.
The high-visibility HD Optic design makes it easy to see switch position—even in low-light engine rooms. Clear labeling reduces mistakes during maintenance or emergency power shutdowns.
Built to handle harsh marine environments, this switch features corrosion-resistant materials and an ignition-protected design for safe installation in engine compartments.
High Current Capacity: Rated for 500A continuous and 2500A cranking, making it suitable for large engine banks and high-draw systems.
Dual Voltage Sensing: Automatically detects and operates on both 12V and 24V systems for maximum versatility.
Optical Sensing Technology: Utilizes advanced optics for precise voltage thresholds, eliminating the mechanical wear found in traditional relays.
Manual Override: Features a control knob for manual "On/Off" or "Auto" modes, providing a fail-safe for emergency parallel starting.
Ignition Protected: Safe for installation aboard gasoline-powered boats (meets SAE J1171 standards).
Status LED: Integrated LED light provides immediate visual confirmation of the switch status.
