Abstract
An electromagnetic relay includes a base, a spool provided on the base, a coil wound on the spool, a yoke inserted into a hole formed in the spool, an armature movably disposed on the base, a movable contact fixed on the base, a static contact fixed on the base, a driving member connected between the armature and the movable contact, and an elastic pressing member fixed on the base. The elastic pressing member is pressed against an outer side of the armature so as to position the armature on the base and provide an auxiliary thrust to the armature.
