Blue Sea Systems WeatherDeck Toggle Switch, For WeatherDeck Panels, IP67 With Boot, 15A @ 12V DC

Overview

The Blue Sea Systems WeatherDeck Toggle Switch is a panel-mount marine toggle switch range made for Blue Sea Systems WeatherDeck panels and available in several switching actions for different circuit-control needs.

These switches use nickel-plated brass and phenolic non-corrosive construction, with 0.25 in quick-connect tab terminals for straightforward wiring inside a helm, cockpit, or exposed switch panel. When installed with a WeatherDeck toggle switch boot, the switch assembly is rated IP67 for temporary immersion up to 30 minutes, which matters on open boats, fishing consoles, wet cockpits, and deck areas that see spray or washdowns.

The range covers SPST and SPDT configurations, with ratings up to 15A at 12V DC, 15A at 125V AC, and 10A at 250V AC, depending on the selected configuration. It is a practical replacement or build-out switch for lighting, horns, wipers, bilge control, navigation light circuits, and other low-voltage marine loads where the switching action needs to match the circuit.

Key features

• Made for Blue Sea Systems WeatherDeck panels, keeping the switch format consistent with WeatherDeck panel layouts.
• IP67 rating for temporary immersion up to 30 minutes when used with a WeatherDeck toggle switch boot.
• Nickel-plated brass and phenolic non-corrosive construction for use in marine electrical panels.
• Available in SPST and SPDT versions to suit simple on/off circuits or circuits that need two controlled outputs.
• 0.25 in quick-connect tab terminals support clean wiring and service access inside the panel.
• Common marine applications include lights, horns, windshield wipers, bilge pump control, dimmer circuits, and navigation or anchor light switching.

Variants

This WeatherDeck Toggle Switch range is offered in multiple action configurations so the switch behavior can match the circuit being wired.

The main differences are the switching action, whether the switch is SPST or SPDT, and whether one or both on positions are maintained or momentary. The WeatherDeck panel fit, IP67 rating with the matching boot, terminal style, and construction are consistent across these variants.

• 4150: Action ON-OFF. This is the straightforward maintained on/off version for a single load, such as a light circuit or accessory circuit that stays on until manually switched off.
• 4151: Action OFF-(ON). This momentary-on version returns to off when released, which suits controls such as horns or windshield wipers where the load is normally active only while the toggle is held.
• 4152: Action ON-OFF-ON. This maintained three-position SPDT version lets one switch control either of two outputs with a center off position, commonly used for circuits such as navigation and anchor light arrangements with independent bulbs.
• 4153: Action (ON)-OFF-ON. This SPDT version combines one momentary on position, center off, and one maintained on position, giving useful control for applications such as manual and automatic bilge pump switching.
• 4154: Action (ON)-OFF-(ON). This SPDT version has momentary action on both sides of center off, which fits controls that should only stay active while the toggle is held, such as certain dimmer or adjustment circuits.

Installation and setup

Match the selected switch action to the circuit before wiring. SPST versions are for a single controlled path, while SPDT versions are used when the circuit needs to switch between two outputs or control modes. The 0.25 in quick-connect tabs help keep replacement work simple, but wire size, fuse protection, and load current should still be checked against the boat’s electrical plan.

For wet locations, install the switch with the correct WeatherDeck toggle switch boot so the panel opening, toggle, and switch body maintain the intended water protection. This is especially important on exposed helms, center consoles, cockpit panels, and any location that can see spray, rain, or routine washdown.

Use cases on board

This switch range fits boats where panel space is limited but the circuit needs a clear, tactile control. The maintained-action versions suit lights and accessories that stay running, while the momentary versions are better for loads that should only be energized while the operator is holding the switch.

It is a good match for owners, riggers, and marine electricians building or servicing WeatherDeck panels on fishing boats, cruising boats, tenders, and workboats where consistent switch fit, wet-area protection with the matching boot, and easy terminal access matter during installation and maintenance.
