[0004] Based on the above, the existing automatic conversion switches are generally divided into automatic adjustment and manual adjustment. When the manual adjustment is made, the power supply needs to be cut off. When the staff adjusts the automatic conversion switch to manual adjustment, the staff forgets to cut off the power supply, and the operation is wrong, resulting in a short circuit. A warning sign is generally set on the surface of the switch, but the nameplate has always been set on the surface of the switch. The staff will ignore the nameplate, resulting in errors in the staff's operation. Utility Model Content

[0014] The utility model adopts a manual warning mechanism to enable the staff to slide the adjustment switch, adjust the automatic conversion switch to the manual mode, and drive the blocking shield to rotate. The blocking shield rotates to display the attention warning plate inside the switch shield, so that the staff can directly observe the attention warning plate. The staff directly installs the attention warning plate prompt to perform adjustment operations, avoiding the problem that the staff forgets to cut off the power supply when adjusting the switch to the manual mode. When the automatic conversion switch is in the automatic adjustment state, the attention warning plate is blocked by the blocking shield, avoiding the problem of confusion in the operation of the automatic conversion switch by the staff, thereby improving the convenience of the staff in operating the automatic conversion switch.

[0015] The utility model adopts a switch installation mechanism to install the automatic conversion switch on the wall through the installation bolts, and the rotation of the installation bolts is restricted by the anti-rotation plug block and the blocking plug hole, thereby avoiding the problem that the installation bolts will become loose when the automatic conversion switch vibrates, and improving the stability of the installation of the automatic conversion switch.
