Screen Printing Surface Mount Tactile Switch Silver Conductive Circuit With 2.54MM Pitch

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
