About this part
Pressure switches sit at the boundary between the hydraulic and electrical systems: they close or open a contact when circuit pressure crosses a set point, driving brake interlocks, warning lamps, pump unloading and safety cut-outs.
We supply adjustable and fixed set-point switches with DIN 43650 connectors, in the pressure ranges normally fitted to crane brake, pilot and main circuits. Piston-type switches are used for high-cycle applications and diaphragm types where fine set-point repeatability matters.
Match the port thread, pressure range and switching function (normally open or normally closed) when ordering.
Ordering information
