Abstract
An electrical relay assembly has a spring action bridge contact for engaging with two counter contact elements. The bridge contact is connected with an armature at one end of a longitudinal first section. The other end of the first section is connected to a linearly directed second section having two contact points facing opposite the counter contact elements. The first section has a lateral width not greater than the distance between the contact points. A lever action of the contact points about two different axes thereby results, as a consequence of which a frictional effect is produced at the contact points. The bridge contact is particularly applicable for the switching of low currents.
