Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belongs to the scope of the utility model protection.
As shown in Figures 1 to 3, a kind of switch, including shell 1, the upper surface of the shell 1 is provided with exterior of finger 2, described outer
Shell 1 is internally provided with circuit board, and lower section and the circuit board of the shell 1 be connected with binding post 3, the binding post 3
It is provided with the through hole 31 for wiring, relative two side of the shell 1 and is provided with shell fragment 11, the shell fragment 11
It is provided with piece tooth 111.
The shell 1 is made up of stratified material, including antistatic backing 101, the first waterproof layer being sequentially connected from outside to inside
102nd, fireprotection layer 103, foamed concrete heat insulation layer 104, plastic basic unit 105, the second waterproof layer 106；The exterior of finger 2
Can be made up of stratified material, including be sequentially connected from outside to inside antistatic backing 101, the first waterproof layer 102, fireprotection layer 103,
Foamed concrete heat insulation layer 104, plastic basic unit 105, the second waterproof layer 106.
The antistatic backing 101 is made up of polyethylene antistatic film, and the function with antistatic can prevent the suction of dust
The attached function of keeping cleaning；The waterproof layer 106 of first waterproof layer 102 and second is by waterproof layer by epoxide resin material system
Into the effect with waterproof is conducive to protecting the circuit structure inside the shell 1, while can prevent rainwater from entering and making
Into short circuit phenomenon；The fireprotection layer 103 is made up of asbestos material, with fireproof function；The foamed concrete thermal insulation separation
Thermosphere 104 is made up of foamed concrete heat preserving and insulating material, the performance with insulation；The plastic basic unit 105 is skeleton,
Effect with support.
The switch is arranged on inside the switch enclosure being adapted to therewith, the both sides that the switch enclosure is adapted with the shell fragment 11
On be provided with opening.During so installing, extruding (shell fragment 11 is bent to the inside) will be switched and enter the box for placing switch
In son, after the shell fragment 11 enters in the box, the shell fragment restores in the aperture position, by the switch card described
In box, because the upper end of shell fragment 11 is provided with gear piece 111, the gear piece 111 can prevent the shell fragment 11 from the box
Opening in slip, for fix it is described switch in the box；When needing to take out the switch from the box,
