Sea-Dog Foot Switch 420430-1, Stainless Steel Momentary Deck Switch for Windlasses

The Sea-Dog Foot Switch, part number 420430-1, is a momentary-contact deck switch designed for hands-free operation of windlasses and other marine equipment. The switch is normally off and turns on only while depressed by foot, then returns to the off position when released, making it ideal for windlass control where continuous foot pressure should be required for safe operation.

Construction is stamped 304 stainless steel with a rubber cover, giving the switch strong corrosion resistance for exposed deck installations. A rubber seal combined with the stainless bezel keeps water out of the switch body, protecting the internal contacts from spray and rain. The switch is rated 12 volts at 30 amps, suitable for direct windlass circuit control.

Installation requires a 2 inch diameter hole to accept the switch body, with an overall footprint of 4-7/16 inches by 3-5/16 inches. The switch bracket can be mounted on the surface of the deck or mortised flush for a lower-profile installation. It installs using ten #8 RH fasteners, which are not included. A replacement rubber seal is available separately for this switch.
