Overview

The knife blade battery disconnect switch is a top post shut off device that interrupts the main battery circuit so power can be isolated without touching a wrench. This 12v/24v battery disconnect switch is aimed at vehicle owners, mechanics, and equipment operators who park machines for long periods, store seasonal vehicles, or need a fast way to kill the electrical system in an emergency. The knife blade battery disconnect switch installs at the battery terminal and provides a simple on/off lever for the whole electrical system.

Good To Know

Q: Will this work on both a 12v car battery and a 24v truck system? A: Yes, the switch is listed for both 12v and 24v applications, so it can be used across cars, trucks, and equipment with either system voltage. Always confirm the terminal style matches your battery before installing.

Q: Does this disconnect switch fit any top post battery? A: It is designed for top post terminal batteries, which are common on many cars, trucks, and pieces of equipment. Check that your battery uses a top post connection rather than a side post or stud terminal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
