Electromagnetic relay with centered contact springs - has centering plate for spring contact set(s) orthogonal to springs motion

摘要

The relay has contact spring set(s) between the magnetic relay par and a centering plate. the centering is carried out in a reference plane orthogonal to the contact spring motion. The contact springs and the centering plate have centering recesses for reception of a centering gauge. The centering recesses are aligned with bores in each contact spring near the contacting points. The recesses in the centering plate have the form of bores, and those in the yoke or armature of bores or notches. These deformations are so arranged as to provide centering facilities for the contact spring set(s). The bores in all components may be formed to receive centering pins of the centering gauge.
