A manual battery disconnect switch (also known as a battery cutoff switch, battery isolation switch, or battery shutoff switch) is installed in an electrical system to allow the operator to completely disconnect the electrical current running through a vehicle or piece of equipment. Being able to isolate the flow of electricity has many safety, security, and cost-saving benefits. With continuous current ratings from 40 A to 600 A, our manual battery disconnect switches are designed for the most demanding environments in all vehicle applications.
- Single-pole and double-pole battery disconnect switch options
- Available actuator styles include push-button, T-handle, rotary knob, key, and lever
- Housings made of various metals or thermoplastic provide solutions for heavy-duty marine and commercial applications
- Portfolio includes water-resistant and waterproof battery disconnect options meeting Ingress Protection (IP) standards from IP43 to IP67 and IPX9K
- If a short circuit causes a fire, a manual battery cutoff switch can be deactivated to prevent further damage to the vehicle or injury to occupants
- For safety, mechanics can ensure a vehicle's electrical system is shut down by operating a master battery disconnect switch
- Using a battery disconnect switch to shut off power to the electrical system of a stored vehicle prevents parasitic loads from draining the battery

What are manual battery disconnect switches?
Installed in an electrical system to allow the operator to completely disconnect the electrical current running through a vehicle, manual battery disconnect switches are used for ensuring the safety of personnel while they work on vehicles, preventing parasitic loads from draining batteries during storage, and safeguarding vehicles from thermal events caused by short
How do manual battery disconnect switches work?
Although some manual battery disconnect switches are push-button emergency cutoff switches, in most cases, manual battery disconnect switches are rotary switches with lever, handle, key, or knob actuators. They may be single-pole, single-throw (SPST) switches for simple on/off functionality, dual-pole, single-throw (DPST) switches, or even single-pole, triple-throw
