Multipole electromechanical switching device

A method of switching electrical contacts comprising:

• monitoring voltage in an electrical system having a power source and a load;
• closing first and second direct current electromagnetically controlled contacts for first and second phases of electrical power at or before a first phase angle determined based on voltage zero-crossing;
• and
• thereafter closing third direct current electromagnetically controlled contacts for a third phase of electrical power at a prescribed moment following the closing of the first direct current electromagnetically controlled contacts;
• wherein the first, second, and third electromagnetically controlled contacts are provided in windows of a common carrier and the window in which the third direct current electromagnetically controlled contacts are disposed is offset with respect to the windows in which the first and second direct current electromagnetically controlled contacts are disposed to provide the closure of the first and second direct current electromagnetically controlled contacts before the closure of the third direct current electromagnetically controlled contacts.
