Since 1962, TER Tecno Elettrica Ravasi has been designing and manufacturing high-quality control devices for lifting and industrial handling machines. Based in Calco, near Lecco (Italy), we supply manufaturers, OEMs, system integrators, and distributors in over 94 countries. Our product range includes rotary and position limit switches, pendant and wall mounted control stations, industrial joysticks, slip rings, cable hoose reels, electronic devices and signal lamps — all developed and assembled in-house to guarantee performance, safety, and full traceability.
Customers turn to us when reliability matters, when customisation is needed, or when projects demand compact, durable, and smart control solutions. We combine mechanical know-how with electronic innovation to deliver products that integrate seamlessly into Industry 4.0 environments.
At TER, quality is a culture: we were the first in our sector in Italy to gain ISO 9001 certification, and we are also ISO 14001 certified.
Our team works closely with clients to solve real application challenges — offering technical expertise, quick response times, and tailor-made solutions. Whether you're developing a crane control panel, upgrading a wind turbine system, or designing a remote operator interface, we help you bring safe and efficient machine control to life.
