Three-position apparatus capable of positioning an electrical transfer switch

A multi-position apparatus for use with an electrical transfer switch having two separate sets of electrical contacts, the multi-position apparatus comprising in combination:

• a position-selection mechanism;
• a first link mechanism and a second link mechanism, each link mechanism being operably coupled with the position-selection mechanism;
• a first weight-actuated spring mechanism operably coupled with the first link mechanism;
• a second weight-actuated spring mechanism operably coupled with the second link mechanism;
• a first output-actuating member operably coupled with the first weight-actuated spring mechanism, the first output-actuating member being arranged to operably communicate with the switch such as to actuate opening and closing of a first set of electrical contacts of the switch;
• and
• a second output-actuating member operably coupled with the second weight-actuated spring mechanism, the second output-actuating member being arranged to operably communicate with the switch such as to actuate opening and closing of a second set of electrical contacts of the switch,
• wherein the multi-position apparatus is configured to position the switch in distinct positions.

A three-position apparatus for use with an electrical transfer switch having two separate sets of electrical contacts, the three-position apparatus comprising in combination:

• a manually-actuated means;
• a first link mechanism and a second link mechanism, each link mechanism being operably coupled with the position-selection mechanism;
• a first weight-actuated spring mechanism operably coupled with the first link mechanism, the first weight-actuated spring mechanism including at least a first weighted cam, a second weighted cam, a first spring, and a second spring;
• a second weight-actuated spring mechanism operably coupled with the second link mechanism, the second weight-actuated spring mechanism including at least a third weighted cam, a fourth weighted cam, a third spring, and a fourth spring;
• a first output-actuating member operably coupled with one of the first and second weighted cams, the first output-actuating member being arranged to operably communicate with the switch such as to actuate opening and closing of a first set of electrical contacts of the switch;
• and
• a second output-actuating member operably coupled with one of the third and fourth weighted cams, the second output-actuating member being arranged to operably communicate with the switch such as to actuate opening and closing of a second set of electrical contacts of the switch,
• wherein the three-position apparatus is configured to position the switch in three distinct positions.
