Compact knob style battery disconnect switches are used to connect or disconnect electrical power from a battery and can help conserve battery life by cutting off power during periods of inactivity. Knob style battery disconnect switches are installed directly onto a battery terminal and work by unscrewing or tightening the battery switch into an “on” or “off” position to control electrical flow.

Tips for Selecting a Battery Disconnect Switch
There are several options available for battery disconnect switches and all provide the ability to conserve battery life and prevent potential theft of your vehicle. Choosing a battery switch depends on preferred style as well as how many amps the switch provides. Your vehicle owner’s manual can provide you with a lot of vital information including power output requirements, but here are a few additional considerations:
- Think about size. Compact battery disconnect switches fit most battery compartments and can be a good choice for smaller vehicles or tight spaces.
- Style is also a consideration in choosing a battery disconnect switch. Options typically include knob style or knife-blade battery disconnect switches, keyed battery disconnect switches for extra safety measures, and heavy-duty battery disconnect switches for industrial applications.
- Mounting options are also important. Top mounted battery disconnect switches are each to see and access, and side mounted battery disconnect switches are more hidden and sometimes preferable for anti-theft applications.
Important Safety Information for Using and Installing Battery Disconnect Switches
- Choose a battery disconnect switch with the correct power output for your battery; choosing one that is too high can blow your switch and damage your battery.
- Always connect to the negative terminal of your battery to ensure proper fit and a reliable connection, and to prevent battery damage or personal injury caused by sparking.
- When removing terminal covers and attaching the battery switch, use caution not to damage any wires.
- After you’ve finished, it’s a good idea to test your switch to make sure it functions properly
