Abstract
The relay includes an "L"-shaped yoke and a cylindrical solenoid core mounted at end thereof in a hole in the short arm of the yoke. The other end of the core is terminated in a pole plate which engages one leg of an angle armature which is pivotally mounted at the end of the long arm of the yoke. The other leg of the angle armature is biased toward the long arm of the yoke by a flat leaf spring. The spring is mounted at one end thereof to the long arm of the yoke and includes a free end which projects through a slot in the other end of the angle armature for engaging a flattened portion of the angle armature at the apex edge of the angle armature. Upon deactivation of the relay, the angle armature is swivelled away from the pole plate until the flat spring is flatly applied to the flattened portion of the angle armature, thereby defining the deactivated end position of the armature.
