WeatherDeck SPST On-Off lever switch

SPST stands for "Single Pole, Single Throw". This indicates that the switch controls a single electrical circuit and has two positions: on and off. It is ideal for simple applications where you want to turn a single device or function on or off, such as a light or a bilge pump.

Yes, BLUE SEA’s WeatherDeck range is specifically designed to withstand demanding marine conditions. This switch is suitable for environments exposed to spray, humidity, and temperature fluctuations, ensuring continuous operation and enhanced durability at sea.

This switch is ideal for on/off control of various onboard equipment, such as navigation lights, bilge pumps, fans, horns, or other auxiliary devices requiring direct control for a single circuit.

This switch is designed for low-voltage electrical systems. It is typically rated for use with 12V DC and 24V DC, making it versatile for most marine installations.

The BLUE SEA WeatherDeck SPST On-Off lever switch (reference 4150-BSS) is designed to handle currents up to 15 amperes at 12V DC and 10 amperes at 24V DC. It is critical not to exceed these values to ensure the safety and longevity of the switch.

For installing this switch, a standard 13 mm (1/2 inch) drilling diameter is typically required. This allows for flush and secure mounting in most marine control panels or dashboards.

This switch uses 6.35 mm (1/4 inch) quick-connect terminals (faston) for wiring. Use proper terminals and ensure a secure connection for optimal performance and electrical safety.

Yes, the BLUE SEA WeatherDeck SPST On-Off switch is compatible with 12V DC and 24V DC electrical systems, making it versatile for a wide range of marine applications.

No, this specific lever switch (reference 4150-BSS) is not backlit. It provides a simple on/off function without integrated illumination.

Yes, BLUE SEA’s WeatherDeck design ensures this switch is particularly suited and resistant to the salt and corrosive environments typical of marine use, guaranteeing long-term durability and reliability.

Yes, thanks to its standard format and common hole diameter, this switch is designed to make replacing similar-sized existing switches easier. Just make sure to cut the power before any intervention.

Although the switch itself does not contain an integrated fuse, it is strongly recommended to install an appropriate fuse upstream of the switch in the electrical circuit. This protects the switch and the connected equipment against overcurrents and short circuits.

The lever is the physical control element of the switch. By toggling it, you change the state of the electrical circuit, switching from the "On" (on) to "Off" (off) position or vice versa, thereby enabling or disabling the connected device.

Absolutely. The "WeatherDeck" designation indicates that this switch is specifically designed to withstand harsh marine outdoor conditions, including exposure to spray, rain, and UV rays, ensuring its reliability even when mounted on deck.

A detailed wiring diagram is typically not included for a simple SPST switch, as the connection is straightforward (one input, one output). However, basic wiring principles are easily accessible, and it is always recommended to consult a professional for any complex installation.

Yes, like most BLUE SEA products, this switch is covered by the manufacturer’s standard warranty. For specific details regarding the duration and warranty conditions, refer to the information provided by the manufacturer or retailer.
