The Littelfuse ALT115-S-SW alternating relay is designed for electrical applications needing precise control. Offering reliable performance, it alternates between two loads, making it useful in duplex pumping applications. The built-in switch allows for manual operation of a pump when needed, providing flexibility in maintenance and testing.
This alternating relay is ideal for balancing the runtime of both pumps in duplex systems. It features a built-in debounce to prevent state changes due to momentary switch bounces. Suitable for industrial automation and power distribution, it ensures continuous operation with space-saving design.
