Four Color Mate Surface Membrane Key Pad With LED Illuminated
Digital printing and screen printing are two distinct printing techniques that differ in their approach, capabilities, and applications. Here are the key differences between the two:
Features
-
Operation:
- When a button is pressed, the top layer makes contact with the underlying circuit, completing an electrical connection that sends a signal to the device.
-
Construction:
- Composed of several layers, including a flexible printed circuit board (PCB), a spacer layer, and a top overlay that has printed graphics.
-
Durability:
- Generally resistant to dust and moisture, depending on design specifications. However, they may not be as durable as mechanical switches.
-
Design:
- Often customizable in terms of size, shape, and layout, making them suitable for various applications.
-
Cost-Effective:
- Typically cheaper to manufacture than mechanical keypads, making them a popular choice for consumer electronics and appliances.
