Abstract

An electromagnetic hinged-armature relay comprises a contact spring (2) which is arranged on and attached to an armature (1). The contact spring serves as a switching contact spring and has a bounce dampener which is in the form of a swing element (3) made as one piece with the contact spring which greatly reduces bounces of contacts and contact wear resulting therefrom.
