The protective cover comprises a cap and a base, and the cap is hinged with the base through a pin shaft pin hole; the protective cover is arranged on the front panel of the mosaic simulation screen monomer through the base.
Two first openings and a plurality of second openings are arranged on the front panel of the mosaic simulation screen monomer, wherein the two first openings are on the same horizontal plane; the protective cover is fixed on the first opening through a clamping pin on the protective cover, and the switch buttons are arranged in the second openings of the through hole structure.
The block for both ends fold into the lath structure of 90 formation two protruding portions to the homonymy, two protruding portions of block on have a conflict portion, conflict portion can the block upset when extremely the below with mosaic imitation screen monomer surface inconsistent, the position of restriction block upset downwards.
The mosaic simulation screen single body rear end have holding chamber cavity structure holding chamber in be equipped with circuit board assembly to utilize circuit board shell with holding chamber tip block, set up circuit board assembly in the cavity between mosaic simulation screen single body and the circuit board assembly.
The switch buttons 2 arranged on the mosaic simulation screen monomer correspond to the switches on the circuit board assembly one by one.
The reversible cover cap on the protective cover can be freely stopped at any turnover position.
The second opening is positioned below the horizontal plane of the first opening, so that the switch button arranged in the second opening can be covered when the cap in the protective cover arranged on the first opening is turned over to the lower part.
The invention has the following remarkable effects: the protection structure of the combined switch button can shield and protect the switch button by using the protection cover, thereby effectively preventing an operator from mistakenly pressing the switch button or avoiding the switch button from being mistakenly touched by the external environment.
