Innovative Contact Solutions

Our innovative solutions for contacts are designed to address all kinds of problems. Our engineers will be involved at an early stage, collaborating with you during the co-design of your contact and we will be fully in charge of the next steps, from prototyping to final production and delivery. These solutions allow the design of existing products to be modified, and to co-develop new designs according to the original plans of the client.

High precision and customization


We are experts in the manufacture of custom-made electrical contacts, including the production of complex shapes with multiple angles, nano contacts, as well as customized quality control.

High technological capability

We own two high-capacity production plants, thanks to our 500 high-precision machines which produce more than 600 million contacts per year.

About us


Pin crimp

Our miniature pin contacts are manufactured in accordance with the AS 39029 & EN 3155 standards. They are produced with crimp barrel and it is possible to customize the back side to suit any specific requirement.


90° bended socket

Our sockets bend to 90° and tolerant to various conditions, including harsh environments. The pin has been machined in size #20, but we can provide different sizing and bend dimensions upon your request.


Hooded socket with Press-Fit

Hooded socket with pressfit is one of our latest contacts customizations. It has been co-designed and produced in our plants in Switzerland to enable assembly with PCB by tightening. Time savings on the assembly process and cost reduction are among its most significant benefits.


Quality Since

From our Swiss-based company, our engineers will support you from the very first stages of your project: from co-designing the contacts, to manufactured to prototyping development.
