What Is The Distinguishing Feature Of The Hierarchical Structure Of The Membrane Switch

- Jul 26, 2017 -

1. The panel layer
  
Panel generally in less than 0.25 MM layer of PET, PC, such as colorless transparent sheet exquisite design and text on screen printing, because of the action of the main panel layer is the logo and key role, so choose materials must have high transparency, high ink adhesion, high elasticity, prevent fold, etc.
  
2. The cushion rubber
  
Cushion rubber layer is the role of the main panel is closely linked with the circuit layer, to achieve the effect of sealing and connecting, thickness of this layer is between 0.02-0.05 MM, with high viscosity and the aging;In production, generally choose special membrane switch two-side glue, some can waterproof and high temperature membrane switch, so the cushion rubber also must according to the need to use different materials.
  
3. The upper and the lower control circuit
  
This layer adopt good performance (PET) as a carrier of the switching circuit graphics and on its screen printing on the silver pulp by special process of carbon paste or golden syrup has the electrical conductivity, generally within 0.05-0.175 MM, the thickness of the most common is to use 0.125 MM PET.
  
4. The clip rubber

It is in the circuit and the circuit on effect of sealing and the connection between layers, generally used PET double-sided adhesive, its thickness is 0.05-0.2 MM;When choosing this layer material of the product should give full consideration to the overall thickness of insulation, circuit button bag handle and sealing.
  
5. On the back of the rubber
  
Back rubber membrane switch is used to paste is closely related with what kind of material, more commonly used include ordinary double-sided adhesive, 3 m glue, waterproof glue, etc.
