Designed by Power Designs (PDI), the PDF-40R-4M-C-HC model offers a small form factor suited for tight installations in pneumatic or hydraulic systems where an electrical actuation is triggered by pressure. This miniature switch provides a defined pressure-trigger point for automatically switching electrical circuits in compact installations.
