Screen Printing Surface Mount Tactile Switch Silver Conductive Circuit With 2.54MM Pitch
Considerations
- Actuation Force: Choose a switch with the appropriate actuation force for your application to ensure user comfort.
- Lifespan: Check the rated lifespan (usually in terms of cycles) to ensure longevity based on the expected usage.
- Mounting Method: Ensure compatibility with your PCB design, including pad layout and soldering techniques.
Features
- Low Profile: Many tactile switches are low-profile, making them suitable for slim devices like smartphones and wearables.
- Multiple Configurations: Available in various sizes, actuation forces, and pin configurations to suit different applications.
- Compact Design: They are designed to be mounted directly onto the surface of a printed circuit board (PCB), saving space in tight layouts.
- Tactile Feedback: These switches provide a noticeable click or resistance when pressed, giving users physical feedback that the switch has been activated.
Applications
- Consumer Electronics: Used in remote controls, keyboards, and handheld devices.
- Industrial Equipment: Often found in control panels and machinery for operator input.
- Medical Devices: Utilized in portable medical equipment for ease of use.
Selection Tips
- Size and Shape: Consider the physical dimensions and how they fit within your device design.
- Environmental Factors: Look for switches with appropriate ratings for dust, moisture, and temperature if needed.
- Electrical Ratings: Verify the voltage and current ratings to match your circuit requirements.
About Taida.pdf
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
