Contura SPDT On-On red switch with protection

The On-On function means the switch has two stable positions, both active. When the switch is toggled to one position, it remains in that state and powers one circuit. When toggled to the other position, it also remains in that state and powers another circuit (or another function of the same circuit). There is no central "Off" position.

The term SPDT stands for 'Single Pole, Double Throw'. This means the switch has one common pole (one common input) that can be connected to either of two available outputs. It allows switching power from a common circuit to one of two different loads or functions.

This switch is designed to operate with 12V or 24V DC electrical systems, which is standard for marine applications.

The switch can handle a maximum current of 20 amperes at 12V DC and 15 amperes at 24V DC. Do not exceed these values to ensure switch safety and longevity.

The red color of the switch button is primarily used to facilitate its quick visual identification on a dashboard or control panel. This can help distinguish specific functions or draw attention to a particular circuit.

This switch is commonly used to control equipment requiring a choice between two active states. Typical applications include:

Pumps (e.g., toggling between two bilge pumps or two operating modes of a single pump)Navigation lights (e.g., switching between anchor lights and running lights if specifically wired)FansOther equipment requiring a choice between two power sources or two distinct functions.

To install this switch in a panel, a rectangular cutout of 21.08 mm x 36.83 mm (0.83" x 1.45") is required. This is a standard size for Contura-type switches.

This switch is equipped with male quick-connect terminals (faston or spade terminals) of 1/4" (6.35 mm). These terminals are designed for easy and secure connection with corresponding female terminals.

Yes, this switch is designed to the standard Contura format, making it easy to integrate into existing electrical panels and control panels that use this type of cutout and mounting system.

Yes, thanks to its design with protection, the front face of this switch is rated IP66. This means it is protected against powerful water jets and dust, making it perfectly suited for exposed marine environments.

The switch is designed for snap-in mounting in a standard panel cutout. It secures firmly in the opening without requiring screws or additional tools once the cutout is made.

Yes, although designed for robust marine applications, this switch can also be used in other demanding environments where resistance to moisture, dust, and reliability are required, such as off-road vehicles, industrial equipment, or recreational vehicles.

An SPDT On-On switch typically has three terminals:

One common terminal (power input).Two output terminals (one for each 'On' position).Power is connected to the common terminal, and the two loads or functions to control are connected to the two output terminals.When the switch is toggled, it connects the input to either output.

For standard installation in a panel, the switch does not require additional mounting accessories thanks to its snap-in system. However, accessories such as additional sealing gaskets (if not included or if replacement is needed), label holders, or protective caps can be used depending on the application and desired finish level.

Blue Sea Systems Contura switches are typically made from robust, corrosion-resistant materials such as high-quality thermoplastic plastics and internal components in brass or corrosion-resistant alloys to ensure maximum durability in marine environments.

Yes, if the panel cutout is the same (standard Contura format), you can replace an On-Off switch with an On-On switch. However, the wiring must be adapted since an On-On switch controls two active circuits instead of one circuit with an off position.

Yes, this switch can be used to control electric motors, provided the motor's voltage and current do not exceed the switch's maximum specifications (20A at 12V DC, 15A at 24V DC). For more powerful motors, it is recommended to use the switch to activate a relay or contactor to handle the high motor load.

Blue Sea Systems switches are designed for long service life and high reliability. While an exact cycle count is not provided in the description, their robust construction and marine-grade materials ensure excellent resistance to wear and harsh environmental conditions.
