Product Details

K Series

From the trusted RS PRO brand, a series of adjustable pressure switches designed for hydraulic and pneumatic applications. Designed to detect a rise or fall in fluid pressure, the durable switches provide an electrical signal once the setpoint pressure is reached. Pre-set pressure is adjusted via a graduated knob which can be locked with a grub screw. Clockwise to increase the pressure and anti-clockwise to decrease the pressure. Mechanical stops protect both the spring and the micro-switch from over pressurisation.

Robustly constructed from anodised aluminium, the RS PRO pressure switches can be mounted in any orientation making them easy to install in a wide range of industrial environments. Connection via a ” BSPF parallel thread.
