2, due to being equipped with high-performance touch sensible control module at it, make it that there is high stability, reliability and peace
Quan Xing.It can correspond to the switch on and off situation of output port according to the induction number for acting on switch surface, control subsequent conditioning circuit,
The various combination of switch on and off situation can be changed by software programming.
3, each layer making of the chain touch switch of intelligent closestool uses special method of manufacturing technology, to ensure that it works
In stabilization and sure effect.Including：Circuit line, the linear forms in circuit line, line width standard, thickness requirement and the choosing of switch
With material property and manufacturing process.The flow on water droplet and PCB on chain touch switch be two kinds cause false triggering because
Element.Therefore circular ring shape is used in the design of switch, wherein outer shroud is bonding processing, be may be implemented so best
The design scheme of resistance to water induction.
4, the processing technology that switch uses is easy to operate.Silver paste may be used and carry out silk-screen processing on its surface.Control
The present situation, size and silver paste silk-screen layer thickness for making figure are the key that success inductions.
5, the manufacturing cost of film key switch can be significantly reduced, is suitable for producing in enormous quantities.Industry is can be applied to set
The field of the needs such as standby, household electrical appliance and auto parts machinery control switch.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical solution and advantageous effect
It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the guarantor of the present invention
