Contact device
First Claim
1. A contact device, comprising:
- a contact point block including a pair of fixed terminals having fixed contact points and a movable contactor having a pair of movable contact points arranged side by side on one surface of the movable contactor, the movable contact points configured to come into contact and out of contact with the fixed contact points;
a driver that drives the movable contactor such that the movable contact points come into contact and out of contact with the fixed contact points;
a pair of permanent magnets arranged in a mutually opposing relationship across the contact point block along a direction orthogonal to an arrangement direction of the movable contact points and to a direction in which the movable contact points come into contact and out of contact with the fixed contact points, the permanent magnets provided with mutually-opposing surfaces having the same polarity;
a second yoke arranged between the permanent magnets in a mutually opposing relationship to each of the permanent magnets, the second yoke being positioned in an opposing relationship with said one surface of the movable contactor; and
a third yoke that makes contact with the other surface of the movable contactor and opposes the second yoke across the movable contactor.

Abstract
A contact device includes a contact point block, a drive unit, and permanent magnets. The contact point block includes fixed terminals having fixed contact points and a movable contactor having movable contact points arranged side by side on one surface of the movable contactor. The movable contact points are configured to come into contact and out of contact with the fixed contact points. The drive unit drives the movable contactor such that the movable contact points come into contact and out of contact with the fixed contact points. The permanent magnets are arranged in a mutually opposing relationship across the contact point block along a direction orthogonal to an arrangement direction of the movable contact points and to a direction in which the movable contact points come into contact and out of contact with the fixed contact points. The permanent magnets are provided with mutually-opposing surfaces having the same polarity.
