ELECTROMAGNETIC RELAY AND ASSEMBLING METHOD OF IRON CORE OF ELECTROMAGNETIC RELAY

摘要

PROBLEM TO BE SOLVED: To eliminate the dispersion in performance by setting the contact pressure of a movable contact to a normally-opened fixed contact constant. SOLUTION: In this electromagnetic relay, the distance from the armature support part 8g of a frame 8 to a head part 10c is determined by a second distance data Y selected on the basis of the first distance data X from the armature support part 8g of the frame 8 to a normally-opened fixed contact 6, and a press-in part 10a is provided with an iron core 10 pressed and fixed to the iron core fixing part 8d of the frame 8.
