Abstract
Provided is a contact structure for a switch, in which a contact region is increased, a conduction failure can be more precluded, and the operational reliability of the switch can be improved by allowing contact points between contacts to be line contacts. The contact structure for a switch includes a pair of contacts that are opposed to each other to open or close the switch by allowing the contacts to come into contact with or to separate from each other, wherein a contact surface of a first contact is formed into a concave shape provided with a projection and a recess; a contact surface of a second contact is formed into a rounded surface; and the projection of the first contact and the rounded surface of the second contact are configured to come into contact with each other.
