SQ Series Pressure Switch

Introduction – SQ Series Pressure Switch

The SQ Series Pressure Switch is a versatile diaphragm-type pressure control solution designed for reliable performance across a wide range of industrial and commercial systems. Built around an internal diaphragm opposed by a compression spring, the switch activates when process pressure exceeds the spring force, resulting in contact opening or closing depending on the selected configuration. This simple yet robust mechanism ensures dependable pressure control and monitoring within defined or adjustable ranges.

Engineered for durability, the SQ Series offers body material options including 316 stainless steel, zinc-plated steel, and brass—making it suitable for both standard and severe-duty environments. With its diverse selection of contact types, electrical connections, and accessories, it can be configured to match the exact requirements of various hydraulic, pneumatic, and mechanical systems.

The SQ Series Pressure Switch is widely adopted in systems that require consistent and accurate pressure detection, such as braking systems, firefighting hydraulics, lubrication systems, and industrial compressors. Its combination of configurability, high quality, and cost-effectiveness makes it a trusted choice for engineers and integrators across multiple industries.

Dubai Sensor naturally supports the SQ Series Pressure Switch as part of its range of industrial pressure-monitoring solutions, serving customers in the UAE and MENA region seeking reliable and adaptable pressure-switch technology.

Installation, Commissioning & Maintenance

Proper installation begins with selecting the correct pressure range and material configuration suitable for the application. The device should be mounted securely using its threaded process connection, ensuring that the diaphragm receives unobstructed process pressure. Electrical contacts must be wired according to the selected electrical configuration and application requirements.

During commissioning, verify switch operation by applying controlled pressure and confirming that the contact opens or closes at the expected set point, especially for adjustable-range models. Regular inspection is recommended to ensure diaphragm integrity, spring performance, and stable switching behavior. Maintaining clean process connections and periodically checking for mechanical wear will support long-term reliability.
