BRIDGEVILLE, PA, UNITED STATES, October 15, 2025 /EINPresswire.com/ -- Thanks to their distinctive aesthetics, ergonomic design, and enhanced safety features, TOP-KNOBS integrate seamlessly into modern control panels used in applications such as measurement and control systems, laboratory instrumentation, HVAC, communications, and building automation.

Engineered for both form and function, each TOP-KNOB features a robust PA6 main body and a clip-in marking element that conceals the lateral fixing screw while enabling precise

calibration. These marking elements—available in five functional shapes (Pin, Globe, Disk, Wing, and Arrow)—are offered in a palette of soft, modern pastel tones: coral (pink), beach (yellow), lagoon (green), sky (blue), and mineral (gray). The main knob body is available in two standard colors: volcano (gray) and nero (black).

TOP-KNOBS are compatible with rotary potentiometers featuring either round shafts (DIN 41591) or flattened ends. Two secure fixing options are available: push-on or lateral screw fixing using a hex-socket set screw with a cup point. This design ensures electrical safety by eliminating the risk of contact with live components. The recessed underside of each knob accommodates external potentiometer fixing nuts, further enhancing installation flexibility.

Available in five diameters—16 mm, 20 mm, 24 mm, 31 mm, and 40 mm—TOP-KNOBS support boreholes of 4 mm, 6 mm, 1/4", and 6/4.6 mm. Accessories such as M7, M10, and 3/8"-32G round nuts are also available for secure front-panel mounting.

Customization is a key advantage of the TOP-KNOBS range. OKW offers a comprehensive suite of services including CNC machining, pad printing, laser marking, and full assembly of accessories. This enables customers to tailor the knobs to their exact technical and branding requirements.

Designed by Martin Nußberger of polyform Industrie Design, TOP-KNOBS combine contemporary styling with hygienic surfaces and intuitive usability. Their widespread adoption across diverse industries underscores their versatility and the value they bring to modern electronic interface design.
