Beyond dead-centre switching system

摘要

In the case of a beyond dead-centre switching system, which operates with a contact rocker and a tension spring drive, for electrical switching apparatuses, in order to avoid bearing point displacements and friction losses in the region of the eye holders (9, 10) it is provided that at least one of the stamped edges, which are constructed on the eye holders (9, 10), is chamfered in such a manner that a chamfered profile is produced which is like a knife blade or is virtually like a knife blade. <IMAGE>
