Sealed reed contact for telephone systems - has contact bolt with arcing resistance surface, coupled to strip of resetting spring

摘要

The contact elements under magnetic flux are made of permeable material. The reed contact moving armature has a contact bolt extending over the facing surface of the counter contact. The bolt passes through a recess in the contact armature and has an arcing-free contact material on its contacting end. - The contact bolt (5) is connected to a strip (18) formed by slits (15, 16). The strip is formed by a resetting spring (7) which overlaps in parallel direction the contact armature (6), at least partly. Preferably the slits are formed in the resetting spring which is thus divided in three partial strips. The middle strip carries the contact bolt, and the lateral shorter strips are mechanically secured to the contact armature.
