Key Features:
High Current Capacity – 200A Continuous Rating
The switch is built to handle a continuous current of 200 Amps and peak currents significantly higher for short durations (e.g., engine cranking). This makes it suitable for high-power-demand applications such as starting motors, inverters, and auxiliary systems.
Waterproof Design
Designed to resist water ingress, this switch is IP-rated waterproof, making it ideal for marine environments, where exposure to moisture, splashes, or even submersion can occur. It ensures long-term durability without corrosion or electrical failure.
M8 Terminal Studs
Equipped with M8 stainless steel terminal bolts, the switch provides a robust and secure connection. M8 size is widely used in marine and automotive setups for optimal power transmission with minimal resistance and heat generation.
Durable & Corrosion-Resistant Construction
The housing is made from heavy-duty ABS plastic or a similar impact-resistant polymer, combined with corrosion-resistant terminals and components. It withstands saltwater, UV rays, and harsh environmental conditions, perfect for outdoor use.
User-Friendly Rotary Knob with Clear Markings
The switch comes with a clearly labeled rotary dial, allowing easy operation even with gloves or in dimly lit areas. The tactile feedback ensures the operator can feel each position click into place, preventing accidental switching.
