Ampper Side Post Battery Disconnect Switch: Direct-Fit DC Power Control

Keep your electrical system tidy and secure with the Ampper side post battery disconnect switch. Designed for 12 to 48 volt DC systems, it snaps directly onto side-post batteries, eliminating the need for extra cables or lugs.

The robust ABS housing provides a durable protective shell, standing up to outdoor exposure and daily wear. With two simple ON and OFF positions, this switch gives you immediate control over power in cars, RVs, boats, or electrical equipment.

  • Direct fit with no modifications required, making for a clean, quick installation.
  • No need for extra cables or lugs, simplifying the setup process.
  • Wide DC range from 12 to 48 volts, with ON and OFF positions for simple power management.
  • High current capacities (275 A continuous at 12 V, 455 A intermittent, 1250 A momentary at 12 V) for short bursts.
  • Rugged ABS housing with SAE bolts for a durable, safe connection on vehicles, boats, or equipment.

While results can vary by system, the switch offers a practical, tactile way to manage power safely without ladders of wiring.
