Autoelettric S.r.l., founded in 1984, is specialised in the production, testing and development of relays from 10A to 200A, of timer relays and of a complete series of control units for turn signals. We provide bespoke electronic solutions for cars, trucks, motorcycles and all new electrically operated vehicles.

Autoelettric S.r.l. was a traditional production company. Now instead we have become an innovation-oriented company: we aim to develop and produce some strategic product lines entirely in Italy, while maintaining our commitment to test every semi-finished product that we import to our company site.

We consider ourselves a technology company that provides innovative and highly personalised electronic solutions. We place ourselves between the Italian artisan tradition and the automotive industry: the passion and satisfaction that we still feel in making well-made products is a legacy that we carry inside with pride.

Thanks to a privileged and consolidated relationship over time with ZND Zhen De Electronics Co. Ltd of Huangshan (China), Autoelettric S.r.l. has expanded its offer with a wide range of relays for electronic circuit boards (PCB relays and signal relays), industrial relays and relays for various applications in the field of green technologies, directly managing the distribution of branded ZND products throughout Europe.

We are committed to creating an eco-sustainable company, where the workplace is a stimulus for innovation and an opportunity for well-being for the entire staff. Our guidelines are the use of renewable energies, industrial processes with a low environmental impact and energy saving.
