Product engineering design

Nelson Miller Group has broad engineering capabilities and specialized expertise in electronic controls and devices, switches, touch screens, identification solutions, and more.

If you can imagine it, we can design it.

NMG develops solutions that have been applied in an extraordinary number of products: from warehouse lifts to planes, from light switches to touch screen devices, from garage door springs to advanced LED systems, and backlighting solutions. Our customers have used the products we helped design on boats and in space, in hotels and in hospitals, in the home and in harsh industrial environments, and everything in between.

Electronic devices

Our expertise starts with an in-depth understanding of design and materials sciences. We use advanced CAD to quickly develop 3D prototypes and work through options with you. We also utilize simulation software, which is especially critical when using an injection molding manufacturing process or designing backlighting solutions.

Your product’s performance requirements are unique, and our experience is both deep and broad. We tackle design requirements for sophisticated power management systems, extreme environmental conditions (altitude, temperature, weather, humidity), and complex shapes. We find solutions when you have space constraints (thin and small forms), backward compatibility requirements, intricate assemblies, integration of off-the-shelf or other sourced components, or the need to withstand very high actuation cycles.

Total interface solutions

We design total interface solutions and products ranging from basic controls to advanced Human Machine Interfaces (HMI). We use our engineering expertise in electromechanical applications, specialty switches, and touch screens to deliver turnkey solutions. Our range of design expertise includes custom injection-molded plastic components, circuitry (flexible and rigid), printed electronics, light guide films, LED and fiber optic lighting, housings, metal fabrication, hardware integration, wire harnessing, cabling, sealing, finishings, firmware, and Human Machine Interfaces (HMIs).

Specialty switches

We have been designing and producing specialty switches since our inception. We’re intimately familiar with the large variety of manufacturing processes, architecture, and materials. Our design matches your unique application and stringent cosmetic requirements, resulting in highly functional and reliable switches.

We design mechanical, membrane, and capacitive switches. Our engineering and design expertise applies to the three sections of a switch (the overlay, the switch, and the backer), and all the layers in each section. Our design incorporates graphics, windows, embossing, coatings, adhesives, texturing, top circuit, spacers, bottom circuit, and your specific substrate, and even shields, buffers, and tactile domes based on your project’s specific needs. We can incorporate your specialty switches with many different features, including backlighting, touchpads, touch screens, proximity sensors, and more to create a product exclusive to your application.

Touch solutions

We have extensive design expertise in custom touch screens, touch screen overlays, and other touch screen components using resistive, capacitive, and piezoelectric technologies. Your touch screen is custom designed according to your requirements for size, price point, strength, durability, ruggedness, display quality, and application.


We offer the most extensive metal and plastic nameplate processing capabilities in the industry. This means that we can leverage the widest range of technologies to design the exact nameplate you need. With NMG, your design possibilities are endless: We understand multi-color metal anodizing, serializing and UID barcoding, etching and filling, laser etching, silkscreen and digital printing, and polyurethane domed nameplates.

Dials, overlays, and panels

We have expertise in an extensive list of materials and fabrication technologies when designing your dial, overlay, or panel. Our engineering team reviews your product requirements and recommends suitable materials for dials and panels to withstand harsh environments and extend your product’s life. Our design also matches the exclusive look and feel of your brand. Our full-service color lab utilizes solvent- and UV-based chemistries to provide custom color matching to any color, including those that are reflective or transparent, providing you with an impressive and noticeably unique finished overlay.
