力が小さくなり所定の接点間圧力が得られない。The force that presses the movable contact against the fixed contact in the electromagnetic relay, that is, the pressure between the contacts, is given by the magnetic attraction force that attracts the armature to the magnetic poles, and a stable magnetic attraction force is required to obtain a predetermined pressure between the contacts. Must be applied to the poles. For example, if a gap is interposed between the magnetic pole and the armature even if the magnetic pole attracts the armature, the magnetic attraction force applied to the armature becomes small and a predetermined inter-contact pressure cannot be obtained.
