LED push button membrane switch/Flat type membrane switch

      We specialize in manufacturing membrane switches,polydome or metal dome,LED backlight,etc

     Advantages:

1.       Special plastic performance and tightly stick on keypad.

2.       With the infiltration of static the effect of protecting the loop happened.

3.       Manufacturing engineering can be more difficult compared with the exist metal dome

4.       Strong applicability to be the changeable climate.

     Specifications:

1.       Overlay materials:The most commonly used base materials are polyester(PET) and polycarbonate(PC).

2.       Rear adhensive:3M 467MP,3M 468MP,etc.

3.       Standard tolerances:+/-.010inch.

4.       Matching color:panton and RAL color matching system.

5.       Tail,pin and circuit layout:subject to customers detailed requestments.

6.       Type of switch:

(1)    Non tactile

(2)    Graphics

(3)    Tactile with stainless steel domes

(4)    Tactile with poly domes on the circuit.

     Performance:
