Multifunction Switch Panel — Dual USB + Voltmeter + 5 Rocker Switches Key benefits Centralized control: Consolidates charging, voltage monitoring and five switched circuits into one compact panel to keep wiring tidy and accessible. Protects your equipment: Each LED rocker switch includes overload, overcurrent and shortcircuit protection to reduce the risk of damage to connected devices and wiring. Reliable charging and monitoring: Dual USB ports provide DC 5V/4.2A for device charging while the builtin voltmeter monitors battery condition (6–30V detection range) so you can avoid unexpected power loss. Durable in harsh environments: Constructed from ABS, PC and PBT materials for temperature resilience, flame retardance and corrosion resistance, suitable for longterm use and environmentally friendly. Features and specifications Functions: Dual USB socket, digital voltmeter, and five illuminated rocker switches. USB output: DC 5V / 4.2A total. Voltmeter detection range: 6–30V. Switch protection: Each of the 5 LED rocker switches has overload, overcurrent and shortcircuit protection. Materials: quality ABS, PC and PBT for strength, chemical resistance and flame retardant properties. Temperature tolerance: Operates reliably from 25 to 80 C. Compatibility: Designed for 12V and 24V electrical systems. Installation: Prewired for faster installation; includes four stainless steel mounting screws. How it solves common problems Keeps devices charged and accessible: Builtin USB ports eliminate the need for separate chargers or adapters, simplifying onboard charging for phones, tablets and accessories. Prevents electrical damage: Integrated protective circuitry reduces the chance of blown fuses, damaged components or hazardous shorts when multiple devices are used. Monitors battery health: The voltmeter gives a clear, continuous readout of system voltage so you can take action before batteries are depleted or overloaded. Survives tough conditions: Temperature and corrosion resistance extend lifespan in environments prone to heat, cold, moisture or chemical exposure. Practical applications Marine boats: Centralize navigation lights, bilge pumps, USB charging and accessory circuits while monitoring battery voltage in a compact, corrosionresistant panel. RVs and campers: Manage lighting, water pumps, heating fans and mobile device charging from one prewired unit compatible with 12V/24V systems. Trucks and offroad vehicles: Control auxiliary lights, compressors, incab accessories and charge devices while protecting circuits from overloads and shorts.
