22 April 1922

Joseph Siat, engineer, founds the company in Benfeld under the name of the Société des Ateliers de Constructions Électromécaniques du Bas-Rhin (Lower Rhine Electro-Mechanical Manufacturing company). The company manufactures switches, fuse links, fuses, bells, rotisseries and sheet metal or lacquered cardboard bridging boxes.


Death of Joseph Siat. His two sons take over the company, with Pierre in charge of production and Maurice in charge of sales and administration. The company starts to manufacture more specific equipment: changeover switches, transformers, rheostat-regulators and high breaking capacity fuse links.


The company abandons the piecework bonus system in favour of a group bonus. This social innovation, a first in France, gets the full backing of the workforce, now numbering 60 people. The first Works Council is created.


The Société des Ateliers de Constructions Électromécaniques du Bas-Rhin changes its name to Socomec. Social development mirrors technological progress; from 1955 onwards Socomec applies law that links the profit-sharing to gains in productivity. A trade union section is created.


With over 150 employees, Socomec increasingly manufactures products for industrial switchgear purposes: cabinets, switchboards, control consoles, etc. The first integrated sales office opens in Paris.
