The company ELESTA relays GmbH was founded in 1997 as a producer of relays with forcibly guided contacts, but our roots date back to the middle of the last century. Since then, relays have been designed and manufactured in Bad Ragaz in the Swiss canton of St. Gallen. The distinctive feature of these electromechanic relays is the special contact set compliant with EN 50205. All contacts are interlinked in such a way that NC contact and NO contact must never be closed simultaneously, even in case of a fault. Relays with forcibly guided contacts are primarily used in control units for functional...
