Abstract: The application relates to a spring mechanism for a dual power transfer switch and a dual power transfer switch. The spring mechanism includes: a base mounted on a housing of the dual power transfer switch; and a spring mounted on the base. The spring includes a first leg configured to contact and exert a pressure on an indicator of the dual power transfer switch, so as to generate a frictional force between the first leg and the indicator and reduce a rebound of the indicator upon the indicator moving between a first indicating position and an intermediate indicating position, the first indicating position indicates that the dual power transfer switch is in a first power-on position, and the intermediate indicating position indicates that the dual power transfer switch is in a dual-off position.
