Our electrical contact solutions are suitable for various sectors

We are constantly reinventing electrical contact solutions by innovating production processes or by creating new internal standards, in order to optimise assembly with your connectors and create more durable and modifiable products.


By getting involved from the very start of your project, in particular collaborating during the design of the electrical contacts to be manufactured, we can also customize the products to suit your needs.


Operating in the industry since 1965, we are able to produce high-precision pin, socket and inner bodies contacts whose reliability is continually tested, from co-design to production, with a prototype submitted to the client for validation before manufacturing. Our production machines located at our two production sites in Switzerland allow us to perform cutting-edge quality control procedures, such as 100% control on contact retention forces. Thanks to our strict quality control procedures, we strive to achieve production with zero defects with a high tolerance to difficult conditions, including harsh and challenging environments encountered in various sectors such as: Aeronautics and Defence, Space, Industries, Transportation (non-automotive), Medical, Telecommunications, Fiber Optics, Test & Measurement.


Thanks to our know-how and our innovative contacts solutions, we keep expanding our sectors of operations. We count some of the biggest operators in different commercial markets among our clients.
