Designed for power batteries, it allows for quick power disconnection in emergency situations or at the workstation. Ideal for preventing battery drain, maintenance protection, and trailer safety.
What you get with this product
- Instant battery disconnection without tools — a simple turn of the red knob completely breaks the electrical circuit
- Protection against battery discharge when the vehicle is unused for long periods — prevents parasitic consumption of equipment
- Supports a cranking current of 1000A for 5 seconds — compatible with powerful engines and demanding starters
- Installation without major modifications — threaded mounting system and direct connection to battery terminals
- Robust construction from copper alloy and durable ABS plastic resistant to vibrations and extreme temperatures
- Increased safety during maintenance or repairs — eliminates the risk of short circuits or electrocution through complete disconnection
How it works and how to install it
The switch is mounted between the battery and the main electrical circuit by connecting to the positive terminals. The connection diagram included in the package shows exactly how the connection is made: the switch is inserted between the positive pole of the battery and the rest of the electrical system. The OFF position completely cuts off power, and the ON position restores the circuit. Installation only requires tightening the thread through the prepared opening in the access panel and connecting the cables to the terminals at the back. It operates instantly, without delay or power loss.
