Abstract
A switch includes: a first contact and a second contact placed on an operation axis and facing each other; an urging part that urges the second contact to a first contact side; and a second magnetic material part that engages with the second contact to restrict the second contact from moving to the first contact side. The switch also includes: a conductor part that passes current when an arc is formed between the first contact and the second contact; and a first magnetic material part that surrounds the conductor part. When current flows through the conductor part, the second magnetic material part is disengaged from the second contact.
