Abstract
Provided is a contact point structure capable of reducing jitter. The contact point structure mainly comprises a moving contact point and a static contact point. The contact point structure is characterized in that the contacting part of the moving contact point and the static contact point is an inclined surface. When the moving contact point and the static contact point are contacted, the inclined side surface of the moving contact point and the inclined side surface of the static contact point are clung to each other so that the embedded type contacting state is realized. When the moving contact point and the static contact point are separated, the inclined side surface of the moving contact point is separated from the inclined side surface of the static contact point. When the contact point structure is applied to production of an electromagnetic relay, a contactor or a breaker, jitter of the contact points can be effectively reduced so that various relays, the contactors or the breakers which are less in jitter, high in efficiency, low in cost and small in size can be manufactured.
