Screen Printing Tactile Pcb Switch Silver Conductive Circuit With 2.54MM Pitch

Key Features of Tactile PCB Switches:

1. Mounting Options: These switches are designed for surface mount or through-hole mounting, depending on the specific design requirements of the PCB.

2. Size Variability: Available in various sizes and shapes to accommodate different design needs, from compact devices to larger, more complex systems.

3. 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.

4. Applications: Commonly used in consumer electronics, medical devices, automotive controls, and any application needing user input.

5. 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
