In a 12-volt DC environment (automotive, marine, trailer, auxiliary power, etc.) poor connections cause voltage drop, heat, corrosion, intermittent faults and early failure. For example: loose wire-to-terminal contact = higher resistance → more power loss → heat → oxidation → further degradation. A robust terminal solution reduces resistance, limits ingress of moisture/contaminants and resists vibration […]
