Contact spring arrangement for a relay for conducting and switching high

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.

A getter body for use in encapsulated electrical components is of the type consisting of a powder mixture which has been compressed into tablet form. The powder mixture contains in addition to traditional getter material such as activated carbon, zeolite or the like, aluminum stearate and a binder containing a synthetic such as a polyamide. The getter body is produced in several sequential steps. The getter material is mixed with a polycarbonate or a water glass solution, which is then dried and then pulverized. To this first powder is added the aluminum stearate and the binder containing a synthetic. The resulting powder may then be dried and is then pressed into tablets. The tablets may then be heat-cured and are then surfaced polished. The resulting tablets have good abrasion resistance without a noticeable loss in the getter effectiveness.
