Electromagnetic relay and coil terminal

An electromagnetic relay comprising:

• a base;
• a pair of fixed terminals each including a fixed contact and a lower portion fixed to the base;
• a movable spring including a pair of movable pieces, each of the movable pieces including a movable contact contacting and separating from the fixed contact;
• an armature that is coupled with the movable spring, and moves the movable spring by a rotary motion around a fulcrum;
• an electromagnetic device that drives the armature;
• and
• a permanent magnet that is arranged between the pair of fixed terminals, and generates a magnetic field,
• wherein the lower portion and the fulcrum are arranged mutually in opposite directions with respect to the movable contact or the fixed contact,
• the fixed terminals include a first fixed contact and a second fixed contact,
• the movable spring includes a first movable contact and a second movable contact,
• the electromagnetic device is arranged so that an arc generated between the first fixed contact and the first movable contact and an arc generated between the second fixed contact and the second movable contact are extended mutually in opposite directions,
• when a direction of a current flowing between the first movable contact and the first fixed contact and between the second movable contact and the second fixed contact is a first direction, the arc generated between the first movable contact and the first fixed contact is extended in a third direction, and the arc generated between the second movable contact and the second fixed contact is extended in a fourth direction opposite to the third direction, and
• when the direction of the current flowing between the first movable contact and the first fixed contact and between the second movable contact and the second fixed contact is a second direction opposite to the first direction, the arc generated between the first movable contact and the first fixed contact is extended in the fourth direction, and the arc generated between the second movable contact and the second fixed contact is extended in the third direction.
