Contact Device

Abstract: Provided is a contact device with a structure wherein all of three moving contacts can be brought into secure contact with a fixed contact. The contact device is provided with: a fixed terminal (37) that has a fixed contact (35); a movable terminal (28) that comes in contact with and separates from the fixed terminal (37) and that has three moving contacts (31a 31b 31c) that come in contact with the fixed contact (35); and a contact pressure spring (33) that presses the movable terminal (28) and causes the fixed contact (35) to come into contact with the moving contacts (31a 31b 31c) at a predetermined contact pressure. The contact device is characterized by a structure wherein an operating point of the contact pressure spring (33) is located within a triangular region formed by internal tangent lines of the three moving contacts.
