AI Technical Summary
Existing transfer switches lack a limit function, which causes the transfer component to easily shift position under high-intensity use, affecting its service life.
A limit plate and a guide groove are set in the chamber of the conversion switch. The conversion component is driven to move up and down by the operating handle, and the cooperation between the guide groove and the limit plate ensures that the conversion component does not shift in position during the movable displacement process.
This effectively prevents the conversion component from shifting position under heavy use, thereby increasing the service life of the conversion switch.
