This air switch component is used in pneumatic control applications where a push button, air line, or control circuit activates equipment without placing the electrical switch directly at the wet control point. It is especially important to match the switching action, terminal style, rating, and physical configuration because momentary, latching, SPST, SPDT, and DPDT versions are not automatically interchangeable. A correct replacement can help restore reliable equipment activation while keeping the original control layout intact. Because many equipment families use similar-looking parts with small dimensional or configuration differences, compare the existing part, equipment label, plumbing size, voltage where applicable, and part number CRPSEGA-25WR before ordering.
