Our History– Over 100 Years of Innovation

Swelex AB is the result of a successful merger of three companies: Stig Wahlström Elektronik AB, SATCO Komponent AB, and Jolex AB. This is our story – a journey where we have consistently provided cutting-edge technical solutions for more than a century.

Stig Wahlström AB is established with the ambition to provide the Swedish industry with the best possible technical solutions.

To broaden the component range and customer base, SATT establishes a subsidiary named SATTCO.

The personnel at SATTCO buy the company from its publicly traded owner, and the name is changed to SATCO Komponent AB.

Jolex AB is founded, offering a wide range in EMC and shielding, as well as thermal products.

Stig Wahlström AB is divided into three separate companies, and in that year, Stig Wahlström Elektronik AB is formed.

SATCO Komponent AB merges into Stig Wahlström Elektronik AB.

Jolex AB merges into Stig Wahlström Elektronik AB.

With three companies united under one roof, we welcome the new era by changing our name to Swelex AB.
