Automatic electronic switch for bilge pumps – code: 16.610.01 – Osculati

Automatic electronic switch for Osculati bilge pumps (code 16.610.01)

The automatic electronic switch for Osculati bilge pumps, code 16.610.01, is an accessory designed to manage the automatic start and stop of the pump, based on the water level in the bilge. It is a practical solution for onboard systems where reliable pump control is desired without manual intervention, maintaining a simple setting suitable for routine maintenance.

The device is suitable for submersible pumps and is offered as a choice universal for typical applications in the nautical field. Installation can be done in horizontal or vertical position, a useful feature when bilge spaces are limited or when layout constraints of the system must be respected.

Main features and details

Electrical compatibility and field of use

The switch can be used with systems at 12/24 V and is designed to work with submersible pumps within the absorption limits set by the manufacturer.

• Supply voltage: 12/24 V
• Maximum manageable absorption: 20 A (12 V) / 10 A (24 V)
• Intended use: submersible bilge pumps

ON/OFF level intervention logic

Operation is based on predefined level thresholds: the switch activates the pump when the water reaches a certain level and deactivates it when the level drops. This allows automatic management of the bilge emptying cycle, reducing the need for manual control.

• Activation level (ON): 41 mm
• Deactivation level (OFF): 9.5 mm

Anti-false start delay

There is a delay system that helps to avoid unwanted starts due to water movements, swaying, or temporary level changes. This feature is useful in nautical environments, where the bilge may be subject to oscillations and splashes.

• Built-in delay: 3 seconds

Installation and dimensions

The device can be installed both horizontally both vertically, offering flexibility during installation. The dimensions provided help to assess the available space in the bilge and the most suitable position relative to the pump and wiring.

• Mounting orientation: horizontal or vertical
• Dimensions: 92x22x63h mm

Typical onboard applications

This automatic electronic switch is suitable for configurations where you want to automate the operation of the bilge pump, maintaining control based on the water level. It is suitable for installation interventions, refitting, or replacement of an existing control when switching to electronic level management.

• Bilge systems with submersible pumps in motorboats or sailboats
• Maintenance and upgrade of existing drainage systems
• Installations in complex spaces thanks to horizontal/vertical mounting

In contexts where access to the bilge is difficult or where manual operations are preferred to be minimized, an automatic switch can simplify the ordinary management of the system, keeping the pump ready to intervene when necessary.

Operational advantages

Level control automation

Automatic ON/OFF management based on the level allows integrating the pump into a more practical system, limiting operator intervention to periodic checks and maintenance activities.

Reduction of false starts

The 3-second delay is an important functional detail in nautical environments: it helps filter rapid level changes that could cause repeated and unnecessary activations.

Mounting flexibility

The possibility of installation horizontally or vertically allows adapting the component to different bilge geometries and different pump placements, without forcing the arrangement of components.

Integration with 12/24 V systems

Compatibility with 12/24 V makes it suitable for many onboard configurations. It is still essential to respect the indicated current limits and verify the correct circuit protection according to the existing system.

Usage and installation notes

To ensure proper operation, it is advisable to place the switch at a point in the bilge where the water level realistically represents the need to activate the pump, avoiding areas with abnormal stagnation or excessive turbulence. The choice between horizontal and vertical mounting may depend on the available space and the shape of the compartment.

When making electrical connections, it is important to consider:

• the voltage of the system (12/24 V);
• the’power consumption of the pump, which must be within the limits (20 A at 12 V / 10 A at 24 V);
• neat and protected wiring, suitable for the bilge environment.

For interventions on existing systems or in case of doubts about circuit sizing, it is good practice to refer to the recommendations of the pump and onboard system manufacturer, as well as the installation procedures adopted in the nautical field.
