Lemco Precision

What Lemco Precision does

Lemco Précision SA is a privately held Swiss precision manufacturer founded in 1965 and headquartered in Vionnaz, Switzerland, specializing in the co-design and production of high-precision electrical pin and socket contacts, inner bodies, and specialty connector components. The company operates three Swiss sites — a Vionnaz headquarters and Monthey production facility housing more than 500 high-speed screw machines, multi-axis CNC machines, and high-speed transfer machines, and a Biel/Bienne site operated by subsidiary Dorix SA dedicated to gold plating, electroplating, and nickel plating. Production capacity exceeds 600 million contacts per year across miniature (#23–#28), standard, custom, specialty, and innovative contact families, with a stated zero-defect quality target and 98% on-time delivery performance. Differentiated technical capabilities include proprietary SWISSCOAT™ selective gold plating optimization, micro-isostatic removable contact designs for field repair, and in-house R&D machine construction that lowers capital risk and enables custom process development.

Lemco sells exclusively through a direct B2B sales-led motion led by a Head of Sales and Director of Sales & Business Development, supported by application engineers who provide co-design services from initial concept through prototyping and serial production. Pricing is quote-based per project, with multi-year enterprise contracts typical and no public price list disclosed. The company targets seven end-markets — commercial aviation, aerospace and defense, medical equipment, telecommunications (including 5G), fiber optics, industrial, test & measurement, and non-automotive transportation — with named references to Top 10 Aerospace Companies, Top 10 Medical Technology Companies, and civil aviation OEMs as customers. Approximately 90% of production is exported to over 20 countries across four continents, making Lemco an internationally distributed enterprise-anchored manufacturer rather than a regional or domestic supplier.

Revenue is generated entirely from hardware sales of custom and standard electrical contacts, with production runs ranging from small custom batches to high-volume serial orders. The company is led by Chairman and CEO André Rezzonico as sole administrator, and the ownership structure shows no evidence of external institutional investment, indicating organic growth funded internally and through strategic acquisitions — most notably the 2013 merger that formed Lemco Précision and the 2016 acquisition of Dorix SA. EN 9100:2018 (aerospace), ISO 9001:2015, ISO TS 16949, REACH, and RoHS certifications gate entry into regulated end-markets, and the company is investing in a new state-of-the-art headquarters to consolidate its 200+ employee workforce.

Core offering

Lemco Precision co-designs and manufactures high-precision electrical pin and socket contacts, inner bodies, and specialty contacts for the connector industry. Production covers standard, custom, specialty, miniature (sizes #23–#28), and innovative contact solutions, supported by in-house gold plating (SWISSCOAT™), quality assurance, and R&D machine construction, with volumes exceeding 600 million contacts per year across two Swiss production plants.

Product overview

Lemco Precision is a Swiss-based precision manufacturing company specializing in the co-design and production of high-tech male and female electrical contacts and inner bodies for the connector industry. The product portfolio centers on five core contact categories: Standard Electrical Contacts (factory-standard contacts including 90° bended sockets), Custom Electrical Contacts (client co-designed solutions), Specialty Electrical Contacts (application-specific designs), Miniature Contacts (AS 39029 & EN 3155 compliant pin/socket contacts in sizes #23-28 for miniaturized applications), and Innovative Contact Solutions (new designs including removable micro-isostatic contacts). Supporting the core contact products are specialized offerings such as the SWISSCOAT™ gold optimization process for cost reduction. The company operates two high-capacity production facilities in Switzerland with over 500 machines producing more than 600 million contacts annually with a zero-defect target, serving sectors including commercial aviation, aerospace, defense, telecommunications, medical equipment, industrial, fiber optics, transportation, and test & measurement.

Broad incumbents

• Glenair: US-based manufacturer of harsh-environment and mil-spec connectors and contacts. Comparable in aerospace/defense and ruggedized connector focus, though Glenair offers a broader finished-connector portfolio versus Lemco's component-level specialization.
• TE Connectivity: One of the world's largest connector and sensor manufacturers serving aerospace, defense, medical, and telecom. Broad portfolio incumbent that competes in adjacent contact and connector categories but is not specialized in precision-machined contacts like Lemco.
• Amphenol: Global incumbent in interconnect systems including aerospace, military, and industrial connectors. Overlaps with Lemco's pin/socket contact business but operates at vastly larger scale across a much broader product portfolio.
• Radiall: French-headquartered manufacturer of interconnect products for aerospace, defense, telecommunications, and industrial markets. Overlaps with Lemco's pin/socket contact offering as part of a broader connector portfolio.
• Smiths Interconnect: Subsidiary of Smiths Group producing high-reliability interconnect solutions including aerospace-grade contacts and connectors. Comparable aerospace/medical/defense focus but broader product range and corporate-scale resources.
