Built from copper and ABS and rated for a 12V system, it handles high starting currents while offering a low standby draw. The included 9.84 ft (3 m) cable lets you place the control within easy reach, eliminating the need to access the engine bay each time you want to disable or re-enable the electrical system.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this switch stop battery drain?\u003c\/h3\u003e\n\n\u003cp\u003eWhen the switch is turned off, it physically opens the battery circuit, preventing parasitic loads from accessories and aging circuits. Because the device uses high-conductivity copper contacts and flame-retardant housing, it reliably interrupts large currents without significant heat buildup.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eRated Voltage: 12V DC suitable for most automotive systems\u003c\/li\u003e\n  \u003cli\u003eRated Current: 250A continuous; Instantaneous Current: 5000A for cranking surges\u003c\/li\u003e\n  \u003cli\u003eStandby Current: 0.003A for minimal self-drain when engaged\u003c\/li\u003e\n  \u003cli\u003eMaterials: ABS plastic body and copper contacts for stable conductivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I install and operate the control from inside my cabin?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the rocker switch panel is designed for in-cabin mounting and connects with a nearly 10-foot cable so you can place it on the dash or console.
