Abstract: A dual power transfer switch includes a first switch for connecting a first power source to a load and a second switch for connecting a second power source to a load, a user interface configured to receive a user's operating handle for operating the dual power transfer switch, and an interlock device comprising an interlock member which is adapted to act on the user interface to prevent or allow a user to operate the dual power transfer switch through the user interface in accordance with states of the first switch and the second switch. Further, the interlock member is configured to move to different positions so as to lock or unlock the user interface in dependence on different rotation positions of a main shaft of the dual power transfer switch.

Abstract: A dual power transfer switch includes a contact system, which has a contact main shaft rotatably arranged to move contact assemblies. The contact main shaft has a first closed position, a second closed position, and an open position. At the first closed position, the contact assemblies connect a first power source to a load. At the second closed position, the contact assemblies connect a second power source to the load. At the open position, the contact assemblies disconnects from the load. The dual power transfer switch also includes a contact main shaft locking device configured to keep the contact main shaft at the open position. The contact main shaft locking device includes a locking link and a first actuator. The dual power transfer switch includes a contact main shaft interlock device.

Abstract: An interlock device for a bypass device. The bypass device is configured to switch a load between a main power supply and an auxiliary power supply and includes an Automatic Transfer Switching Equipment having a first switch coupled to the main power supply and a second switch coupled to the auxiliary power supply. The bypass device also includes a Manual Transfer Switching Equipment having a third switch coupled to the main power supply and a fourth switch coupled to the auxiliary power supply. The interlock device includes a mounting plate having a first side and a second side opposite to the first side; a first support member arranged at the first side of the mounting plate; and a first interlock assembly configured to prevent the first switch from being closed when the fourth switch is closed.
