• Provides operator-actuated isolation of the main battery from the vehicle electrical system
• Available in single-pole and double-pole circuitry configurations
• Offers multiple actuator styles including push-button, T-handle, rotary knob, key, and lever
• Housings constructed from various metals or thermoplastics for heavy-duty marine and commercial use

Applications

• Trucks and buses
• Construction equipment such as backhoes and bulldozers
• Recreational vehicles and fleet vehicles
• Boats and marine applications

Procurement Notes

Verify the specific continuous current rating and voltage compatibility required for your application before procurement. Confirm the desired actuator style and ingress protection level, as these vary across the product series. Ensure the selected model meets applicable standards for marine or commercial vehicle battery switch applications relevant to your region.

Selection Notes

Select this component based on the maximum continuous current load and system voltage (12 V, 24 V, or 48 V DC). Consider the required ingress protection rating, which ranges from IP43 to IP67 and IPX9K, depending on environmental exposure. Choose an actuator style that suits operational needs and housing material preferences for durability in harsh conditions.
