Switches for Pressure Control
Mechanical pressure switches are devices that use a spring and mechanical sensing element (membrane, bellows or piston) to switch an electrical contact on or off when the system pressure reaches a set value, providing simple and reliable pressure control and protection.
Our range of mechanical pressure switches is available in multiple designs, from low to very high pressures, suitable for applications such as hydraulic systems.

A mechanical pressure switch is an excellent choice wherever a fail-safe opening or closing safety function is required. Typical applications include marine systems, mobile hydraulics, compressor control, and hazardous (potentially explosive) environments.
We offer EX-certified (ATEX/IECEx), marine-approved, and railway-approved versions.
Sensing Elements
1. Bellows
Best suited for low to medium pressure ranges.
- High sensitivity
- Small switching differentials
- Accurate response for delicate systems
Typical use: Precision applications where tight control is required.
2. Membrane
Designed for pressures up to 100 bar.
- Good overpressure resistance
- Compatibility with both liquids and gases
- Balanced performance across industrial applications
Typical use: General-purpose pressure monitoring in process and hydraulic systems.
3. Piston
Engineered for high-pressure environments (up to 600 bar).
- Exceptional overpressure resistance
- Robust construction for heavy-duty use
- Long service life in demanding conditions
Typical use: High-pressure hydraulics and industrial machinery.
