The Perko 8504DP is a reliable medium-duty battery selector switch designed for marine and commercial applications. Featuring a durable polycarbonate body with brass terminals, this switch offers excellent corrosion resistance and mechanical stability. Its compact size, with a diameter of approximately 5-1/4 inches and a depth of 2-5/8 inches, makes it suitable for tight engine compartments and panel installations. The switch's key lock mechanism ensures secure operation, preventing accidental switching and ensuring the safety of your electrical system. Built to operate within 6 to 32 volts, it supports a continuous current capacity of 250 amps and can handle up to 360 amps for 5 minutes intermittently, making it ideal for demanding marine environments or heavy-duty vehicle applications. The terminal stud size of 5/16 inches ensures compatibility with standard wiring setups, while its ignition-protected design enhances safety during engine operation. This switch is particularly beneficial when used with non-unitized alternators, as it interrupts the field current when turned off with the engine running, reducing the risk of alternator damage or electrical faults. Its straightforward installation and robust construction make the Perko 8504DP a trusted choice for managing multiple battery sources efficiently and securely in your electrical system.
