Hydraulic Switches / Transducers

Precision Monitoring for Fluid Power Systems

Hydraulic switches and transducers are essential components in modern hydraulic systems, enabling accurate monitoring, control, and automation. By converting physical variables like pressure or force into readable electrical signals, these devices help ensure safe, efficient, and responsive system performance.

At Hydraulics Online, we supply a wide range of hydraulic switches and transducers from leading global brands – with impartial advice to help you find the right solution for your application.

Hydraulic Switches are devices that activate or deactivate an electrical signal when a set pressure threshold is reached. They’re commonly used for system protection, feedback loops, and automated control.
Hydraulic Transducers are analogue devices that convert one form of energy into another – typically transforming pressure, force, or motion into an electrical signal. This process, known as transduction, allows hydraulic systems to interface with electronic control units, displays, or data loggers.

These components are often found at the intersection of automation, measurement, and control – especially in high-speed or safety-critical systems.

Hydraulic transducers and switches are used across a wide range of industries and systems, including:

Mobile machinery and off-road vehicles
Industrial automation and robotics
Marine and offshore equipment
Aerospace and defence systems
Renewable energy and power generation

They play a key role in:

Monitoring system pressure and triggering alarms or shutdowns
Providing real-time feedback to controllers or PLCs
Enabling closed-loop control for precision performance

We offer a broad selection of components to suit different system requirements:

Pressure switches – for on/off control based on pressure thresholds
Electrical pressure transducers – for continuous monitoring and signal output
Compact and robust designs – suitable for harsh environments
Wide pressure ranges – to match low, medium, and high-pressure systems
Analogue and digital compatibility – for integration with modern control systems

Need help selecting the right device? Our technical team is here to assist.

We supply hydraulic switches and transducers from a wide network of manufacturers, including many leading global brands. Whether you’re replacing a legacy unit or specifying a new system, we offer:

Access to 80+ hydraulic brands
Expert support for product selection and compatibility
Export and logistics services across seven continents

As an independent supplier, our recommendations are based on your system needs – not a manufacturer’s catalogue.

What’s the difference between a switch and a transducer? A switch provides a binary on/off signal when a set condition is met, while a transducer continuously converts a physical variable (like pressure) into an electrical signal.

Are these components compatible with digital systems? Yes – many transducers offer analogue or digital outputs suitable for integration with PLCs, HMIs, and other control systems.

Can I use these in high-pressure environments? Absolutely. We supply components rated for a wide range of pressures and environmental conditions.
