Abstract:
Provided is a contact device in which all of three movable contacts can be securely brought into contact with fixed contacts. The contact device includes a fixed terminal 37 that has a fixed contact 35, a movable terminal 28 that moves toward and away from the fixed terminal 37 and has three movable contacts 31a, 31b, and 31c that are brought into contact with the fixed contact 35, and a pressing spring 33 that presses the movable terminal 28 and brings the movable contacts 31a, 31b, and 31c into contact with the fixed contacts 35 at a predetermined pressing force. The point of application of the pressing spring 33 is located in a triangle formed by internal tangents of the three movable contacts.
