[0002] A dual-power conversion switch is a switchgear that can automatically switch the load circuit from one power supply to another standby power supply in case of main power failure or power outage. Its original design intention is to ensure that critical loads can operate continuously and reliably in case of power failure, avoiding production stoppages, equipment damage or more serious consequences.

[0003] When assembling the existing dual-power conversion switch, each part is installed layer by layer on the base. After all the parts are installed, the upper cover is finally assembled. However, this structure is not conducive to assembly line production. Generally, it can only be assembled through one assembly line, resulting in low production and assembly efficiency.
