EAO

What EAO does

EAO AG is a Swiss, family-owned manufacturer of Human Machine Interface (HMI) components and systems, founded in 1947 and headquartered in Olten, Switzerland. The company designs and produces rugged push buttons, keypads, joysticks, rotary controllers, selectors, indicators, emergency-stop switches, charging solutions and complete HMI control panels organized around named product series (notably Series 09, 82, 84, 57, 51 and 04). Technical differentiation centers on harsh-environment durability (IP67/IP6K9K ratings), functional safety (DIN EN ISO 13849 PL d, ISO 26262 ASIL B), industrial communication integration (CAN bus, LIN, IO-Link, M12), antimicrobial Clean Touch coatings, programmable RGB halo illumination, and an award-winning 3D Online Product Configurator. Manufacturing is concentrated at the Olten headquarters and at the Auerbach (Vogtland, Germany) site, which is being expanded into a central European logistics hub for the group.

EAO serves six primary verticals — Railway, Heavy Duty Vehicles, Special Vehicles, Buses & Trucks, Industrial Automation & Equipment, and Automotive — with named blue-chip customers including Stadler Rail, SBB, SNCF, Trenitalia, Alstom, CAF, CRRC, Liebherr, Volvo, Hitachi, CNH Industrial, ABB, Bosch Rexroth, Beckhoff, Rosenbauer and Versalift. The business model is B2B hardware-led, combining catalog sales of standardized components with customer-specific adaptations and full custom HMI Solutions projects priced via quote-based multi-year contracts. Distribution is hybrid: owned sales subsidiaries in 12 countries (Switzerland, Germany, France, Italy, Netherlands, UK, US, China, Hong Kong, Japan, South Korea, India) complemented by global distributor and representative networks, supported by trade-show presence at InnoTrans, APTA, Vertikal Days, CIIF and EIMA, and by a self-serve digital configurator channel. The company holds a deep certification stack (IRIS, TSI PRM, EN 45545, CE, CCC, CQC, CSA, EAC, ENEC, E1, UL, UKCA, DNV, EHEDG, IATF 16949, ISO 9001:2015) and reports ~600 employees serving customers in more than 50 countries.

Revenue is not publicly disclosed and EAO is privately held with no external investment backing identified. Recent strategic activity is concentrated around the "EAO Future Auerbach" manufacturing transfer and logistics hub build-out, the extension of the Series 09 rugged product family (including a functionally safe PREMIUM variant and a marine entry), expansion of the EAO Charging Solutions line, and incremental vertical coverage via a new Business Development Manager for heavy-duty and commercial-vehicle markets. The company has received external recognition including iF Design Awards (2022, 2026), a Railway Technology Excellence Award 2025, and an EcoVadis Bronze Medal in 2026.
