From the trusted RS PRO brand, a series of double contact adjustable pressure switches designed for hydraulic and pneumatic applications. Designed to detect a rise or fall in fluid pressure, the robust switches provide an electrical signal once the setpoint pressure is reached. Pre-set pressure is adjusted by rotating a screw which is located in the centre of the switch head. Clockwise to increase the pressure and anti-clockwise to decrease the pressure.

Robustly constructed from steel, the RS PRO pressure switches can be mounted in any orientation making them easy to install in a wide range of industrial environments. Compact in design the switches are ideal for designs requiring a small footprint. Connection via a “BSP parallel Male thread. Electrical connection DIN 43650 IP65 plug.

RS PRO Adjustable pressure switches are suitable for a diverse range of industrial applications. Due to their versatility and simple design, the switches can be used in both pneumatic and hydraulic systems. Some of the more common are

• Pumps
• Compressed air systems
• Machine tools
• Process control equipment
• Sensors
• Hydraulics and Pneumatics
• Valves and switches

297-0052 does not include a mechanical stop and requires a 2mm allen key in order to adjust

This pressure switch can be switched between 20 – 300 Bar with a max pressure rating of 400 Bar.

Pressure Switches

Pressure switches that allow microswitch operation once a pre-set pressure is reached. K and K3 Series incorporate a mechanical stop providing over-pressure protection for the spring and microswitch. Electrical connections for all models to DIN 43650.
