Or fluid sealant sealing prevents steam from entering；Picking out pick out the end encryption seal or fluid sealant sealing of line prevents steam from entering.
When being sealed using fluid sealant or sealing ring, in process of production, using ultrasonic technique, melts plastic cement and make cable
Rubber and access case colloid it is molten be integrated, prevent seam, prevent steam from entering.
Water is that cannot enter the inside metal contact completely with vapour above switch button, achievees the purpose that waterproof.
Steam enters other parts in order to prevent, including panel, panel-switch key, panel sealing circle, switch fixing casing are close
Seal；
Face plate center includes that the logical heart is open, and panel snaps fit onto on the switch fixing casing, switch fixing casing sealing ring position
Lead to heart opening in the face plate center, panel sealing circle is located at face plate edge；
Panel-switch key leads to heart opening by face plate center, snaps fit onto on the switch button, rotary panel on ＆ off switch
The rotation of switch button is driven, movable contact flat is driven, movable contact flat is made to switch in two states.
Between the terminal box and switch fixing casing, including terminal box sealing ring, prevent steam from passing through terminal box and switch
Gap enters between fixed plate.
Further include back box, different installation specification demands can be adapted to, the terminal box is connected with the back box by screw
Connect or buckle clamping.
Switch button is with the same ultrasonic technique of sealing ring with switch-mode metal contact point；Water is with vapour above switch button
The inside metal contact cannot be entered completely；
Above-mentioned switch button pass includes but not limited to：Push switch, rotary switch, audio-switch.
When using audio-switch, panel-switch button is non-functional type decoration panel, and panel sealing circle is that centre is not opened
The gasket seal of mouth prevents steam entrance.
The advantageous effect of the present invention compared with the prior art is：First is uses terminal box sealing plate flexible, by movable part
Part bottom end is closed firmly so that the metal parts of switch internal is sealed with external moisture.
Second for using sealing ring, prevent steam by the gap access switch between non-movable member inside.
