Mechanical Pressure Switch – Adjustable Relay Output for Air, Water & Hydraulic
A robust, adjustable mechanical pressure switch designed for reliable on/off control in air, water, and hydraulic applications. Featuring relay signal output and compatibility with 125–250V power supplies, it is ideal for pumps, compressors, and industrial control systems.
This mechanical pressure switch provides dependable pressure-based switching for a wide range of industrial and commercial systems. Designed for use with air, water, and hydraulic media, it delivers simple and reliable relay-based control without the need for complex electronics.
The switch operates within standard 125–250V power systems and outputs a relay signal suitable for directly controlling pumps, compressors, solenoid valves, contactors, and alarm circuits.
An adjustable setpoint mechanism allows technicians to configure the cut-in and cut-out pressure thresholds to suit specific system requirements. Its alloy housing provides durability and resistance to mechanical wear, making it suitable for workshop, plant, and equipment integration.
With an operating temperature range from −10°C to 100°C, the unit is well suited for industrial machinery, HVAC systems, water boosting systems, hydraulic power units, and general process automation.
