Screen Printing Keypad Switch Panel Silver Conductive Circuit With 2.54MM Pitch
Applications
- Gaming: Custom controls for gaming setups.
- Medical Equipment: Input controls for devices in healthcare settings.
- Smart Homes: Control lighting, HVAC, and security systems.
- Commercial Settings: Employee access and monitoring systems.
Key Features of Keypad Switch Panels
- Feedback Mechanism: Visual (LEDs) or auditory (beeps) feedback to confirm input.
- Durability: Resistance to environmental factors, especially in industrial settings.
- Button Layout: The arrangement of keys, which can be numeric, alphanumeric, or function-based.
- Integration: Compatibility with various systems, such as microcontrollers or home automation hubs.
- Customization: Ability to program keys for specific functions or commands.
Considerations When Choosing a Keypad Switch Panel
- Connection Type: Wired (e.g., USB, RS-232) vs. wireless (e.g., Bluetooth, Wi-Fi).
- Size and Form Factor: Ensure it fits the intended space.
- Number of Keys: Based on the complexity of tasks to be performed.
- Power Supply: Battery-operated vs. hardwired options.
- User Interface: Ease of use is critical, especially in high-traffic areas.
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, UV resistance
Polycarbonate:
1.Different surface(Glossy, Matt) and thickness(From 0.12mm~2mm)
2. cost-effective in price
3.For internal and external use
2) Embossing
Rim embossing/pillow embossing/dimple embossing
Graphic overlays can be embossed in order to insert domes/LED, leave space for mechanical keys/LED and provide tactile indications and better tactile feeling.
3)Windows(for display function)
1. print different colors windows, As transparent grey/Red/green window for display
2. Clear/Transparent window for LCD display
2. Matt/semi-transparent window for LED
4)Keys/buttons
Tactile keys---with metal dome or poly dome
Non-tactile--silver printing dots with flat key
5) Embeded LEDs
Small, brilliant lights only about 0.02’’ in height. Avaliable in several vibrant colors.
LED colors: white, yellow, orange, green, red, or double colors LED.
6)Cable
It 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, acrylic, PCB
