Marine Single-Pole Toggle Switch (WeatherDeck, 2 or 3 Positions)

This single-pole toggle switch is built to meet the rigorous demands of marine electrical panels. Commonly used in WeatherDeck series panels, it features a corrosion-resistant construction: the main body and bushing are brass with nickel plating, and the toggle lever has a chrome-plated finish for extra protection and a sleek look. The switch’s compact footprint (approx. 28.8 mm x 17.0 mm mounting size) allows it to fit in high-density switch panels found on smaller boats and dash consoles. Despite the small size, it’s robust, with contacts capable of handling up to about 15–20A (sufficient for most lights and moderate loads – for higher currents it’s recommended to drive a relay). A rubber O-ring or gasket under the toggle and at the panel interface provides weather-resistance, so the switch can endure rain or spray when mounted on exposed dashboards (often rated to the same standards as WeatherDeck – splash-proof when properly installed). We offer multiple versions under the same series to cover different control needs:

• 2-position ON-OFF (maintained) – a simple two-position toggle that stays either on or off. Use this for devices like lights or power switches that you want to turn on and have remain on until turned off manually.
• 2-position (ON)-OFF (momentary) – a two-position spring-loaded toggle that returns to “OFF” when released. This momentary on type is ideal for functions like horn or manual bilge pump override, where you only need the circuit active while holding the switch.
• 3-position (ON)-OFF-ON – a three-position single-pole toggle with momentary in one direction and maintained in the other. In our specific offering, one side is momentary (spring return) and the other side is latching. This configuration is perfect for bilge pump control switches that offer “AUTO – OFF – momentary MANUAL” operation, for example: one stable ON position to engage an automatic float-switch circuit, center OFF, and a spring-return ON for manual pump activation.
• 3-position ON-OFF-ON (maintained) – a three-position single-pole double-throw switch that stays in any of the three positions (no spring return). This is useful when selecting between two power sources or two circuits (like switching between two banks of lights, or selecting either of two devices to power on).
• 3-position (ON)-OFF-(ON) – a momentary in both up and down positions (with center off) single-pole toggle. While less common in single-pole form, this could be used for two momentary functions sharing one switch (for example, two discrete trim tab solenoids if wired separately, or a windshield washer with dual momentary outputs).

All these switches are single-pole (SP) devices, meaning they switch one circuit (one input, one output) – the 3-position variants are SPDT (single-pole double-throw) allowing the common input to connect to one of two outputs. They snap neatly into modular switch panels or can be mounted individually with a retaining nut (depending on design, some are press-fit). The toggle action is crisp, and the internal contacts are silver alloy to ensure low resistance and reliability over tens of thousands of operations. The WeatherDeck compatibility indicates it’s part of a line that is often combined with snap-on rubber boots for full waterproofing (boots can be added on the toggle lever if needed for IP67 exposure, available separately). The lever is relatively short to avoid accidental breakage and is smooth with a rounded tip. In practical terms, these switches can control nav/anchor lights (using the ON-OFF-ON variant to switch between “Nav” and “Anchor” circuits), act as a pump selector (auto/off/manual), or simply toggle any ON/OFF accessory on board. With their brass and stainless internals, they resist rust and perform reliably in the marine environment. If you’re refitting or customizing a control panel, these single-pole toggle switches from the WeatherDeck series will provide a professional-grade solution with a solid tactile feel and proven longevity.
