An electrical switching apparatus includes an enclosure having an opening, a single operating handle disposed through the enclosure opening, a first pole disposed in the enclosure and including first separable contacts, a first operating mechanism to open and close the first contacts, and a first operating member cooperating with the first operating mechanism to open and close the first contacts. A second pole is disposed in the enclosure and includes second separable contacts, a second operating mechanism to open and close the second contacts, and a second operating member cooperating with the second operating mechanism to open and close the second contacts. The single operating handle, centered between parallel poles, includes a first projection within the enclosure cooperating with the first operating member to open and close the first contacts, and a second projection within the enclosure cooperating with the second operating member to open and close the second contacts.
