Abstract
A switch includes a first contact and a second contact that are placed along an operating shaft and can reciprocate with respect to each other. An end of the second contact opposite to an end thereof on the side of the first contact is housed in a housing space of a housing box. The pressure in the housing space is increased due to an arc generated when the first contact approaches the second contact. The increased in the pressure causes the second contact to move toward the first contact.
