Screen Printing Tactile Pcb Switch Silver Conductive Circuit With
2.54MM Pitch
Key Features of Tactile PCB Switches:
Mounting Options: These switches are designed for surface mount or through-hole
mounting, depending on the specific design requirements of the PCB.
Size Variability: Available in various sizes and shapes to accommodate different
design needs, from compact devices to larger, more complex systems.
Tactile Feedback: Users can feel a distinct response when the switch is pressed,
making it easier to use in applications where confirmation of
actuation is important.
Applications: Commonly used in consumer electronics, medical devices,
automotive controls, and any application needing user input.
Durability: Many tactile switches are rated for a significant number of
cycles (often in the hundreds of thousands), ensuring long-term
reliability.
Considerations When Choosing Tactile PCB Switches:
- Travel Distance: The distance the switch must be pressed to activate can affect
user experience.
- Environmental Ratings: Some switches are designed to be water-resistant or dustproof.
- Actuation Force: The amount of pressure required to activate the switch can vary,
so choose one that suits your needs.
- Electrical Ratings: Ensure the switch can handle the voltage and current of your
application.
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
