Telma AG

Telma AG is an independent company with many years of experience in industrial electronics. Control units for the use in apparatus construction, machine construction, building and railway technology have been at the heart of our product range since the very beginning.

We offer an entire range of services from consulting and concept development, through to industrialisation, production and maintenance. By combining development and production under one roof our customers save valuable time and money.

We also develop and manufacture “in-house” products such as:

  • Leak detectors for the prevention of water damage
  • Optical warning systems to display the operating status of overhead and third-rail lines in railway and transport companies’ workshops
  • Water disinfection using silver ions for industrial and drinking water
In electronics manufacturing services (EMS), we have specialised in meeting Swiss customers’ requirements and in producing medium quantities at competitive costs. Our offer includes procurement of components, SMD and THT assembly as well as the assembly and testing of complete devices.

Telma is committed to Switzerland as a manufacturing location and is expanding its capacity further with the new building in Seftigen. A skilled workforce and modern machinery mean proven products and a guarantee of high manufacturing quality. To ensure our business has sufficient qualified personnel in the future, we attach great importance to the promotion of young talent and the training of electronics technicians.
