WeatherDeck SPST momentary Off lever switch

SPST stands for "Single Pole, Single Throw". This means the switch controls a single circuit (one pole) and has only one switching position for that circuit (one direction).

BLUE SEA's WeatherDeck series is specifically designed for marine environments. The switches in this series are made from corrosion-resistant materials, resistant to water spray and humidity, ensuring reliable performance even in harsh conditions aboard a boat.

The switch is made from marine-grade materials, selected for their resistance to corrosion, UV exposure, and humid environments. This typically includes technical plastics and treated metal components.

Yes, this switch is designed to be water-resistant. It has an IP67 protection rating for the front face when properly installed with its sealing gasket. This means it is fully protected against dust and can withstand temporary immersion in water (up to 1 meter for 30 minutes).

To install this lever switch, a mounting hole with a standard diameter of 12.7 mm (0.5 inch) is required in the panel.

This switch can be installed on panels with a maximum thickness of approximately 4.06 mm (0.16 inch). It is important to check your dashboard thickness before installation.

The switch is equipped with two 6.35 mm (0.250 in) male faston-type connection terminals. For connection, corresponding female faston terminals must be used and then connected to the electrical circuit wires.

Yes, to ensure waterproofing and achieve IP67 ingress protection rating on the front face, it is essential to use the sealing gasket provided or recommended by the manufacturer when installing in the panel.

Generally, this switch is supplied with essential mounting accessories such as a mounting nut and a washer, as well as a panel gasket. It is advisable to check the contents of the packaging upon receipt.

An SPST (Single Pole, Single Throw) switch has two connection terminals: one input terminal for the current and one output terminal for the controlled circuit.

Yes, this switch can be used to control inductive loads such as small motors, pumps, or fans, provided the starting and operating current of these devices does not exceed the switch’s maximum rated current (15A at 12V DC, 10A at 24V DC).

Yes, as a product in BLUE SEA’s WeatherDeck series, this switch is specifically designed to withstand harsh marine environments, including exposure to salt, moisture, and UV, thanks to the use of marine-grade materials.

No, there is no specific orientation required for the lever during physical installation. The switch will operate the same regardless of its orientation. However, for aesthetic or functional consistency on a dashboard, a standard orientation may be preferred.

Blue Sea Systems switches are known for their robustness. While an exact value is not always specified, they are designed to provide long mechanical service life, supporting a large number of on/off cycles, which is essential for reliable use in marine environments.

No, this specific lever switch (model 4151-BSS) is a basic model and does not include built-in lighting, indicator light, or backlighting.

Yes, thanks to its WeatherDeck design and IP67 rating, this switch is perfectly suited for outdoor use on a boat, whether on dashboards or consoles exposed to the elements.
