Master Disconnect Switch 2 Pole w/ Removable Key

The Master Disconnect Switch 2 Pole w/ Removable Key (EA0-0460) is a critical safety and security component for any serious automotive project, whether you're building a competition vehicle, restoring a classic, or securing a modified car during storage and transport. This OMP Racing disconnect switch cuts primary and secondary battery circuits simultaneously, isolating all electrical systems in seconds. It's engineered for race cars, off-road builds, show vehicles, and high-performance street machines where rapid power shutdown is essential for safety compliance, pit work efficiency, and theft prevention.

The two-pole design manages both positive and negative battery feeds independently, ensuring complete circuit isolation and eliminating the risk of residual drain through parasitic loads or grounded electrical paths. The removable key mechanism adds a critical security layer—when the key is removed, the switch cannot be accidentally or deliberately reactivated, making it ideal for vehicles left unattended at events, in storage, or on trailers. OMP Racing's design prioritizes durability and reliability, with a compact footprint (6 x 2 x 8.75 inches) that integrates cleanly into engine bays, battery boxes, or interior trim without consuming excessive space or creating installation complications.

This disconnect switch is favored by race teams, fabricators, and automotive enthusiasts running carbureted or fuel-injected engines in competition, drift, autocross, and street-strip applications. Installation requires routing battery cables through the switch terminals and securing the unit to a stable mounting point with adequate clearance for key insertion and removal. The removable key feature meets many sanctioning body safety requirements for organized events, while the two-pole configuration provides peace of mind for any build where electrical isolation and vehicle security matter. Compact at 0.3 lbs, it adds negligible weight while delivering professional-grade circuit control and long-term reliability in demanding automotive environments.
