Pressure Switches for Industrial Systems

Reliable Pressure Switches for Any Custom Solutions

SUCO pressure switches are precision-engineered devices that automatically control electrical circuits based on the pressure of a fluid, whether liquid or gas. 

Pressure switches are essential components used across various industries, including industrial automation, HVAC systems, food and beverage processing, mobile machinery, hydraulic systems, and pneumatic equipment. These reliable devices monitor system pressure levels, trigger alarms, and activate control mechanisms to safeguard equipment, prevent system failures, and ensure optimal operational performance. Widely adopted for their durability and accuracy, pressure switches play a critical role in maintaining safety and efficiency in diverse industrial applications.

SUCO offers precision performance under extreme conditions, including high pressure, temperature fluctuations, and heavy vibration, ensuring reliable operation even in the most demanding environments.

Types of Pressure Switches

high pressure switches

High Pressure Switch

These high-pressure switches offer exceptional durability, with overpressure safety ratings up to 8,700 psi (600 bar). Their ability to withstand pressures far beyond their normal switching point makes them highly reliable and well-suited for demanding or harsh operating environments.
low pressure switches

Low Pressure Switch

Low pressure switches provide accurate and reliable control of small pressure changes, making them essential for pneumatic systems, HVAC, and low-pressure fluid monitoring. Their sensitive diaphragm ensures precise switching and protects equipment in applications that require low-force pressure control.
Highest Protection Pressure Switch ATEX

Explosion Proof Pressure Switch

An explosion-proof pressure switch is a sealed, heavy-duty device that safely monitors pressure in hazardous areas by preventing internal sparks from igniting flammable gases, vapors, or dust. It provides reliable, compliant pressure control in high-risk industrial environments.
integrated pressure switch

Integrated Deustch Pressure Switch

Integrated pressure switches are used to provide reliable pressure monitoring in harsh, mobile, and outdoor environments. They feature a built-in Deutsch electrical connector, which offers a secure, waterproof, and vibration-resistant connection.
Snap Action Pressure switches

Snap Action Pressure Switch

A snap-action pressure switch quickly changes state when a set pressure is reached, providing fast, accurate, and reliable pressure control for efficient operation and equipment protection. It’s widely used in HVAC, compressors, pumps, and industrial systems across various demanding applications.
electronic pressure switch

Electronic Pressure Switches

SUCO electronic pressure switches offer high-precision, durable pressure monitoring with advanced silicone-on-sapphire or ceramic sensors, programmable setpoints, and robust stainless-steel construction. They deliver stable, reliable performance in harsh industrial and hydraulic environments.
