Benefits

A battery disconnect switch can make routine vehicle and equipment maintenance more convenient by providing a dedicated point for manual electrical isolation. It can also help reduce unwanted battery drain during periods when compatible equipment is stored or not being used.

The compact rotary format allows the switch to be operated quickly while the contrasting indicator markings provide a simple visual reference for the selected position.

Important Safety & Compatibility Information

Important: This is a generic electrical component. Confirm the exact voltage, continuous current rating, peak current rating, terminal dimensions, wire size and installation requirements before use. The supplied image confirms a 12V–48V indication but does not provide enough information to guarantee the switch's exact current rating or compatibility with every vehicle or electrical system.

Installation should be performed with the power system safely isolated and according to the requirements of the specific vehicle or equipment. Incorrect installation or use of an unsuitable switch can result in overheating, electrical damage or other hazards.

Product appearance, terminal configuration and packaging may vary slightly between manufacturing batches. Please compare the actual product dimensions and specifications with your application before ordering.
