How is the membrane switch sorted?

From:admin Date: 2017-06-19
Membrane switch structure: divided into convex and flat.
Raised the structure of the membrane switch: switch keys slightly rise, slightly higher than the panel, constitute a three-dimensional shape of the membrane switch. Stereo button can accurately determine the orientation of the key body, progress to identify the speed, aroused the operation
The author is sensitive to touch.
Flat film switch: the initial stage of the membrane switch is more prevalent. The buttons on the membrane switch only use the color to express the orientation, shape and size of the key body.
Membrane switch material classification:
1, polycarbonate (PC): temperature -60 ~ 120 ℃ / thickness 0.125 ~ 1.2 / smooth, high light transmittance, environmental protection, low water absorption, good scale stability, bending, tensile strength Very superior.
2, polyester (polyethylene terephthalate PET): temperature -30 ~ 160 ℃ / thickness 0.075 ~ 0.25 / smooth, resistant personality outstanding, insoluble in the usual organic solvents, alkali.
3, polyvinyl chloride (PVC): temperature -20 ~ 60 ℃ / thickness 0.175 ~ 1.5 / smooth, at room temperature on the acid, alkali and salt stability. Good wear resistance, fire self-extinguishing, muffler shock, electrical insulation is good. Heat stable
Poor sex.
The above three points is today for everyone to bring the classification of the membrane switch, I hope to help you, if you have a demand for our products, we look forward to working with you!
