1962 : celduc was founded
celduc, which is a contraction of Construction Electriques DU Centre (electrical construction of the centre), was founded in 1962 by Michel Guichard the grandson of the famous Geoffroy Guichard.
celduc is the result of the merger of two companies acquired by Michel Guichard. La Scare, a Saint Chamonese company specialising in fine winding and small transformers, and Transformateur Industriel, located in Grenoble.
1964 : celduc moved to Sorbiers
In July 1964 the two sites of Saint Chamond and Grenoble moved to Sorbiers. It is the starting point of the great celduc’s adventure.
celduc started out by manufacturing electrical coils of all sizes. Thanks to its new Sorbiers factory, celduc is detaching itself from subcontractors to launch its own products.
1965-1966 : Launching of the first Reed Relays
Thanks to its new Sorbiers factory, celduc is detaching itself from subcontractors to launch its own products. Still in 1964 celduc has acquired a manufacturing licence for REED switches.In 1965 we rapidly developed a new range of products with “Reed” relays, small low-current switches which were popular at the time for their unrivalled service life.It was in 1966 that the first reed switches left the Sorbiers factory.
