Poly Dome PET Circuit Custom Membrane Switch Keyboard With Silver Paste
A Poly Dome Membrane Switch is a type of membrane switch that utilizes polyester (PET) or polycarbonate (PC) material for the dome switch layers. This construction offers several distinct features and benefits
Poly Dome Membrane Switches are widely used in a variety of applications, including consumer electronics, medical devices, industrial controls, and automotive interfaces, where durability, tactile feedback, and customization are important factors.
Membrane Switch specification:
1)Material---for front or face overlay
Polyester
1.Highly versatile for embossing 2.Highly resistant to chemicals
3.Better durability 4.For internal and external use
Polycarbonate
1.Wide range of surface finishes and thicknesses
2.More cost-effective 3.For internal and external use
2) Embossing--rim embossing pillow embossing dim embpssing
Graphic overlays can be embossed in order to insert domes (tactile), leave space for mechanical keys and provide tactile indications Pedestal embossing
3)Windows ----for display function
1. print colors windows
2.transparent finishes windows
4)Keys/buttons
Tactile keys---with metal dome or poly dome
Non-tactile--silver printing spot
5) Embeded LEDs-
miniature LED, LED colors:white, yellow, orange, green, red, etc.
6)Cable
is an extension of the printed circuit and is used to communicate with your device
7)Types of connector
1.Zero insertion force (ZIF) connector; 2.Female connector; 3.male connector
8) EMI / RFI / ESD Shielding
use an aluminum foil shielding / a clear ITO electrical conductive polyester
9) Adhesive ----mostly used are 3M-double-side glue
10)Backplate---in aluminum, polycarbonate or acrylic
