About us

The company Semax AG was founded in 2011 by Severin Fischer. In the same year, the company took over the representation of Elster GmbH for the whole of Switzerland. Even then, the focus was on electricity meters and metering systems.

Thanks to the broad product range and local expertise, demand has risen steadily. Semax is therefore expanding and today employs more than 40 people in production, sales, engineering and development.

Our products and solutions are used by around 130 small and medium-sized utilities as well as large electricity companies. For many years, Semax has been assisting various utilities throughout Switzerland with the roll-out of smart metering solutions and is available to provide support and advice.

We have been manufacturing Honeywell Elster AS3000 and AS3500 electricity meters in Cham since 2015. We label and parameterise the devices according to individual customer requirements. The production process, including calibration and testing, is carried out in accordance with MID and national approval (CH).

Semax has been active on the market with two smart metering systems since 2017.

Semax has been ISO:9001 and ISO:27001 certified since 2018.

Since 2019, Semax has been active as a system integrator for smart metering systems in Switzerland. We offer the full range of services from meter parameterisation, communication, system and interface engineering to the digitalisation of smart metering processes.

Semax has been working with Ensor AG as a project partner in various projects since 2020.
