An electrical contactor comprises a first electrically conductive cantilevered arm (201) carrying a first contact (203) adjacent its fixed end and a second contact (204) adjacent its free end and a second electrically conductive cantilevered arm (205) carrying a third contact (207) adjacent its fixed end and a fourth contact (208) adjacent its free end. The first and second arms are arranged in opposed alignment such that the fixed end of one arm is opposite the free end of the other arm, the first contact (203) is aligned with the fourth contact (205) and the second contact (204) is aligned with the third contact (207). A first terminal (206) connected to the fixed end of the first arm (201), and a second terminal (202) connected to the fixed end of the second arm (205). The arrangement of the first and second arms (201, 205) is such that when the first (203) and fourth (208)contacts and second (204) and third (207) contacts are closed current flowing between the first (206) and second (202) terminals through the first (201) and second (205) arms produces an attractive force between the first (201) and second (205) arms. |
