Blue Sea Systems 4163 Push Button Switch, Red LED, OFF-(ON) Momentary, 10 Amp

The Blue Sea Systems 4163 is a panel-mount push button switch built for marine electrical circuits that need a compact, waterproof momentary control. It operates OFF-(ON), meaning the circuit is closed only while the button is pressed and springs back to OFF on release, with a red LED ring that illuminates to show status. The switch is rated 10A at 12V DC, making it suitable for accessory circuits, horns, bilge pump test buttons, windlass controls, and other momentary-contact applications where continuous ON operation is not wanted.

Construction is sealed to IP67 with an O-ring panel gasket and a molded rear cover, protecting the internal contacts from spray and washdown. The switch is reverse polarity protected, guarding the circuit against wiring mistakes during installation. Termination is via 5 x 0.110 inch quick connect tabs, which are included, allowing a solderless wiring connection at the back of the panel. It mounts through a 3/4 inch diameter panel hole and fits panels from.04 inch up to.31 inch thick, covering most fiberglass and composite helm panels.

This switch is part of the Blue Sea Systems push button switch line, which shares a common footprint and mounting hardware across amperage and LED color variants, so panel cutouts stay consistent if a boat owner standardizes on this switch family.
