Product Overview

Lemco Précision SA has been a specialist in the production of high-precision screw machine pin and socket contacts as well as the production of  inner bodies since 1965. We machine products of all sizes, including nano contacts.

 

Our expertise lies in the production of highly sophisticated electrical contacts according to the drawings of our clients and in collaboration with our experienced professional engineers, designers, and plant technicians.

 

All of our products are manufactured to tight tolerances, from prototyping to the daily production of low, medium, or high volumes thanks to our 500 machines located at our two Swiss production plants. They are all subject to strict quality controls. The contacts we produce can be used in various types of connectors, circular connectors, rectangular connectors, triangle connectors, printed circuit boards (PCB), and custom-made products.

 

Our expertise is widely recognised in the production of crimp removable standard contacts according to the AS 39029 and EN3155 standards used in harsh environments, in addition to providing custom-made contacts and solutions for the international connection market.

 

No matter your request, we are committed to helping you and providing technical support in the development of your contacts, from prototyping to the delivery of mass-produced parts. Our team members are available to answer any questions you may have throughout the process.

 

Submit your design to us and we will produce it with a high level of quality control and a focus on 100% zero defaults target along with on-time delivery.

Miniature Contacts

Innovation and customer focus are in our DNA. This is why we created our own standard miniature contacts based on the AS 39029 & EN 3155 standards design, in order to keep up with the international market trend of miniaturization and provide our clients with the latest and best technology. Contacts are available in various sizes, from #23 to #30 on active area. Miniature contacts allow the density to be increased, along with reducing the size, pitch, weight, and space on connectors.
