Title: CONTACT SYSTEM FOR CAM SWITCH AND A CAM SWITCH INCLUDING THE SAME
Abstract:
A contact system is provided. The contact system includes a fixed contact (20); a moving contact (10) configured to be in connection with or released from the fixed contact; a contact carrier (30) having a first side and a second side and movably carrying the moving contact at the second side; a cam (40) configured to press the contact carrier from the first side; and a spring (50) configured to press the contact carrier from the second side through the moving contact, wherein the contact carrier has an arc portion at the second side to be in contact with the moving contact. A cam switch including the contact system is also provided. The contact system can lower the possibility that the moving contact is side-tumbled or offset, promote the elimination of the heat, reduce the temperature, and decrease the possibility of fusion welding with the simple structure and high performance.
