The ISURE MARINE Battery Disconnect Switch is designed to safely cut off battery power, effectively preventing excessive drain when your vehicle or boat is idle. This quick disconnect mechanism is ideal for use in 12-48V DC systems, enabling you to isolate and secure your electrical circuits.

Scope of Application:
This versatile switch is not limited to cars, RVs, trucks, and marine vessels; it is also suitable for various electrical devices including flashing lights, chassis lights, fog lights, and dome lights.

Important Note:
The switch is rated for a maximum continuous current of 275A. It is crucial not to exceed this rating for extended periods to avoid the risk of burning out the switch. Additionally, please follow the wiring diagram strictly; incorrect wiring will prevent the switch from effectively disconnecting power.

Installation Tips for Battery Kill Switch (12V):
1. Remove Cables from Battery: Disconnect both positive and negative cables from the battery terminals to ensure safety. 2. Disconnect Negative Cable Terminal: Carefully remove the negative cable terminal. 3. Wire in the Switch: Install the switch between the cable and the battery terminal to ensure that it breaks the connection to the battery when in the OFF position. Confirm that the switch remains in the "On" position during installation. 4. Reconnect the Terminal: Reattach the negative cable terminal. 5. Secure the Switch: Fasten the switch firmly to the frame or your chosen mounting location. 6. Reconnect Battery Cables: Finally, reattach both the positive and negative battery cables to complete the installation.

User-Friendly ON/OFF Switch:
The switch features a clear ON/OFF knob; "ON" (=1) signifies a closed circuit, while "OFF" (=0) indicates a cut-off circuit.

Durability and Security:
Constructed with brass terminals, the switch boasts a modern, sleek look while ensuring robust durability. It includes a removable rear cover designed to insulate the rear terminals, preventing short circuits. The fully enclosed design protects internal wiring from dirt, corrosion, and moisture. The operation is smooth yet firm, ensuring it remains securely in either position.

Performance Specifications:
When activated, the switch powers up your electrical system; deactivating it cuts off the power. It can handle continuous DC power of up to 275 Amps for one hour, intermittent use of 455 Amps for five minutes, and momentary cranking power of 1250 Amps lasting 10 seconds. It is equipped with dual 3/8" (10mm) studs.
