Document Type and Number:
WIPO Patent Application WO/2023/141995
Kind Code:
A1
Abstract:
Embodiments of present disclosure relates to a dual power transfer switch. The dual power transfer switch comprises 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 (50) configured to receive a user's operating handle (60) for operating the dual power transfer switch, and an interlock device comprising an interlock member (70) which is adapted to act on the user interface (50) to prevent or allow a user to operate the dual power transfer switch through the user interface (50) in accordance with states of the first switch and the second switch, wherein the interlock member (70) is configured to move to different positions so as to lock or unlock the user interface (50) in dependence on different rotation positions of a main shaft of the dual power transfer switch. With these embodiments, the user interface can be interlocked in dependence on different rotation positions of a main shaft of the dual power transfer switch, which improves the safety of the dual power transfer switch.
