Type of buttons for membrane keyboard:
Non tactile
Tactile with stainless steel domes
Tactile with poly domes on the circuit
The main properties of custom design electronic membrane keyboard
1. PC /PET as overlay (control panel)
2. Flat keys or tactile type
3. Embossed button with good tactile feel
4. Pre-assemble with or without metal domes
5. Water-resistant, dust-proof, gas-proof and scratch-resistant
6. Long life cycle.

Flexible Printed Circuit Board (abbr. FPCB) .
FPCB is minimization , slimness , high technology for whole digital products which are getting smaller , slimmer.Compare with the rigid printed circuit board , FPCB has the following advantages :
(1) light, thin, short, small, flexible structure, can be bent, curled, folded, and three-dimensional assembly, adapter can replace a lot of parts, easy to use maximum available space, making electronic products become more slim in appearance, widely used has a small, lightweight and mobile requirements of all kinds of electronic products ;
(2) high heat resistance, can produce higher density and finer pitch products to meet the high density interconnect between the components and the high stability requirements, so that a larger increase the quality of the signal output ;
(3) can be wound transfer roller processing methods (Roll-to-Roll), easily automated, mass production, improve production efficiency.
Notice: We have the capacity to provide you membrane keyboard with other special requirements, such as Shielding, Windows/Lens Coating, Embossing, Embedded LEDs, UV glossy/matte/textured, EL,LED backlingt,rubber keypad etc.
