Product catalogue 2014 - Relays with forcibly guided contacts-3

What started out in 1997 as the continuation of ELESTA AG‘s traditional relay production with just 15 employees, became a globally operating innovation leader in the area of functional safety and relay technology. Now latest relay products and sensors are produced by over 250 employees. These products are often the centrepiece of safety circuits of machinery and equipment. Every day we encounter many of those products without noticing them. Thus ELESTA products guarantee safety when we use elevators, ride the train, at the hospital, but also when we celebrate stars on stage or when movie heroes...
