Control electric winches with your finger or foot. The Harken single-function waterproof switch is engineered for reliable, safe control of electric and hydraulic winches, furlers, and windlasses in demanding marine environments. Designed for on-deck installation, it features a protective guard that prevents accidental activation while still allowing precise fingertip operation through the top opening for fine adjustments. When more power is needed, the flip-up guard enables foot activation, freeing both hands for tailing lines or managing gear. Built for durability and ease of use, this marine-grade switch offers dependable performance in wet, salty conditions, making it an essential control solution for serious sailors and boaters.
