Overview
Riese electronic was a German manufacturer of electronic components and assemblies, founded in 1958 by Roland Riese in Stuttgart. The company began as a development firm for electronic assemblies and devices, and over the following decades grew into a supplier of relays, safety switching devices, timing and measuring relays, and custom electronic solutions. Its primary customers were in the automation and safety technology sectors. At its peak, the company operated sites in Horb am Neckar and Langenwolschendorf, and held a stake in an electronics manufacturing services (EMS) operation in Hungary. The company's history reflects both technical ambition and structural challenges. After moving to Schönaich near Böblingen in 1964 due to capacity constraints, it developed the control system for the world's first electronic ticket machine that same year. In 1969, it relocated again to the Hohenberg industrial area in Horb am Neckar, which remained its headquarters until closure. A branch plant opened in Zeulenroda-Triebes in 1991 and later moved to the neighboring municipality of Langenwolschendorf in 2008. The company reorganized into two main business areas: Electronic Manufacturing Service, offering development, production, and testing of customer-specific electronic assemblies and devices; and Automation & Safety, producing components for automation and safety technology, including safety switching devices, timing and measuring relays, and measuring instruments for the concrete industry. Ownership and management evolved over time. From 1998, Oliver Riese served as managing director and owner. In 2013, Roland Haidysek became second managing director. The company filed for insolvency in 2014 and was closed on 1 July 2015. Despite the insolvency, the legal entity Riese Electronic GmbH continued to exist, owned by members of the Riese family and Roland Haidysek. The brand is now defunct as an operating business, but its legacy remains in the niche of industrial relays and safety electronics.
History
Riese electronic was founded in 1958 by Roland Riese in Stuttgart as a development firm for electronic assemblies and devices. Due to a lack of capacity, the company moved to Schönaich near Böblingen in 1964. In the same year, it developed the control system for the world's first electronic ticket machine. In 1969, again due to capacity constraints, the company relocated to the Hohenberg industrial area in Horb am Neckar, where it maintained its headquarters until its closure in 2015. In 1991, Riese electronic opened a branch plant in Zeulenroda-Triebes, which moved to the neighboring municipality of Langenwolschendorf in 2008. The company also held a stake in an EMS operation in Hungary. The company underwent a realignment of its business areas. The Electronic Manufacturing Service division offered services, development, production, and testing of customer-specific electronic assemblies and devices. The Automation & Safety division supplied components for automation and safety technology, including the manufacture of safety switching devices, timing and measuring relays, and measuring instruments for the concrete industry. From 1998, Oliver Riese served as managing director and owner. From 2013, Roland Haidysek was second managing director. The company filed for insolvency in 2014 and was closed on 1 July 2015. The entity Riese Electronic GmbH continued to exist after the insolvency and remained owned by members of the Riese family and Roland Haidysek.
