Abstract

An electrical contact device (X) includes a first contactor with contact portions (C, C) and a second contactor with contact portions (C, C). The device (X) also includes an electrical circuit having a branch path (YA) provided by the contact portions (C, C) and a branch path (YB) provided by the contact portions (C, C). When closed, the branch path (YA) has a smaller resistance, and the branch path (YB) a greater resistance. In a closing operation, the first and second contactors approach each other. Then the contact portion (C) and the contact portion (C) contact with each other after the contact portion (C) and the contact portion (C) contact with each other. In an opening operation, the first and second contactors separate from each other. Then the contact portion (C) and the contact portion (C) separate after the contact portion (C) and the contact portion (C) separate.
