RELAY OPERATING ELECTROMAGNET COMPRISING PLURAL COILS MOUNTED ON A U-SHAPED CORE AND A FREE-FLOATING ARMATURE

摘要

(Case No. 6984) IMPROVED ELECTROMAGNETIC STRUCTURE FOR A VITAL RELAY An improved electromagnetic relay structure employing a multiple coil U-shaped electromagnet, a flat spring biased armature and a single piece U-shaped metallic frame for providing a floating hinge joint and a teeter point for the armature whereby the magnetic attractive pull on the armature is enhanced without diminishing the amount of armature movement.
