Gardner Bender 41860 Battery Cutoff Switch 50A 12V

Product Description

The GARDNER BENDER 41860 is a 2-position battery cutoff switch rated for 12 volts and 50 amps, designed to fully disconnect a battery from a vehicle or equipment electrical system. The switch follows a simple on-off sequence, giving technicians and installers a reliable means to isolate the power source during service or storage. It mounts through a 0.5-inch hole, making installation straightforward on panels, consoles, or enclosures. Electricians, marine technicians, and automotive service professionals install this type of switch as both a safety disconnect and an anti-drain device. The red and black color scheme indicates the on and off positions clearly.

This battery cutoff switch suits 12-volt DC applications including automotive, marine, RV, and light equipment installations. It is appropriate for any scenario where a hard disconnect between battery and load is required, such as long-term vehicle storage, race car safety requirements, or routine electrical service on mobile equipment. The on-off function makes it a practical addition to any DC panel or battery box where a simple, accessible isolator is needed by service personnel.

Compatibility

Designed as an OEM-style replacement or new-installation battery cutoff switch for 12-volt DC electrical systems requiring a 50-amp rated on-off disconnect.

Installation Notes

A licensed electrician or qualified technician should install this switch in compliance with applicable NEC or vehicle-specific wiring codes. Disconnect and fully discharge any capacitive loads before beginning installation, and confirm the battery is disconnected before making terminal connections. Use appropriately rated wire gauge and terminal hardware to match the 50-amp rating of the switch. Do not exceed the rated voltage or amperage, and verify that the mounting panel material is suitable for the mechanical and electrical demands of the application.
