OEM Custom Matrix Design Mebrane Tactile Button Keypads With Glossy Surface
A Matrix Metal Dome Switch, also known as a Matrix Switch or Dome Switch Matrix, is a type of input device that utilizes a matrix-based architecture and metal dome switch technology.
Key features and characteristics of a Matrix Metal Dome Switch include:
Matrix Design:
The matrix design is created by arranging the switch contacts in a grid-like pattern, typically with rows and columns.
This matrix structure allows for a compact and efficient layout of multiple switch inputs.
Metal Dome Switches:
Each intersection point in the matrix grid is equipped with a metal dome switch.
The metal dome provides the tactile feedback and actuation mechanism when the user presses the corresponding key or button.
Scanning and Encoding:
The matrix design allows the system to scan the rows and columns to detect which switch has been pressed.
The scanning and encoding circuitry can then interpret the switch actuation and translate it into a specific input signal or command.
Flexibility and Scalability:
The matrix architecture enables a high degree of flexibility in terms of the number of inputs (keys/buttons) that can be accommodated.
Additional rows and columns can be added to the matrix to expand the input capabilities as needed.
Cost-Effectiveness:
The matrix design and metal dome switch technology can be cost-effective to manufacture, especially for applications requiring a large number of inputs.
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
