Switch

A switch comprising:

• a fixed contact including a fixed contact point;
• a movable contact including a movable contact point contactable with the fixed contact point, the movable contact being disposed to be movable in a first direction with respect to the fixed contact;
• a magnetic field generating member disposed apart from the movable contact in a second direction orthogonal to the first direction, the magnetic field generating member including a first magnetic pole surface facing the movable contact and a second magnetic pole surface facing a side opposite to the movable contact;
• a main yoke including a first connection portion and a pair of arm portions, the first connection portion being connected to the second magnetic pole surface, extending from the second magnetic pole surface in a third direction orthogonal to both the first direction and the second direction, and projecting to one side and another side in the third direction farther than each of the magnetic field generating member and the movable contact, and the pair of arm portions extending in the second direction from both end portions of the first connection portion along the third direction and being disposed on both sides of the magnetic field generating member and the movable contact along the third direction;
• and
• an auxiliary yoke directly connected to the first magnetic pole surface, wherein
• the auxiliary yoke includes:
• a second connection portion directly connected to the first magnetic pole surface;
• and a pair of extending portions extending farther than the first magnetic pole surface in the third direction from both end portions of the second connection portion along the third direction, and extending so as to approach the movable contact as advancing away from the second connection portion.
