High-Quality Medium Duty Battery Selector Switch

The Perko 8504DP Medium Duty Battery Selector Switch is a top-tier product designed for marine electrical systems. This switch offers reliable performance and a host of features that make it an essential component for any boat. Constructed with a durable polycarbonate body and brass terminals, this switch ensures long-lasting use in harsh marine environments.

Key Features and Specifications

The Perko 8504DP features a robust design with a diameter of 5-1/4" and a depth of 2-5/8", making it suitable for various applications. It is ignition protected, ensuring safety in high-risk environments. This switch is designed for use with 6 to 32 Volt marine electrical systems, providing versatility for a wide range of boats. With a continuous amperage of 250 AMPS and a peak amperage of 360 AMPS for 5 minutes, it can handle heavy loads without failing. The terminal stud size is 5/16", ensuring a secure connection. When used with non-unitized alternators, the switch interrupts the field current, reducing the risk of damage if turned "OFF" with the engine running.

Practical Applications and Benefits

The Perko 8504DP Medium Duty Battery Selector Switch is an ideal choice for boat owners looking for a reliable and high-performance switch. Its lockable design ensures that the switch cannot be tampered with, providing peace of mind. With two positions and a continuous amperage of 250a, this switch is capable of handling a wide range of electrical demands. The box dimensions of 3"H x 6"W x 8"L and a weight of 0.95 lbs make it easy to install and maintain. Don't miss out on the opportunity to upgrade your boat's electrical system with this top-quality Perko switch.
