Screen Printing Momentary Tactile Push Button Switch Silver Conductive Circuit With 2.54MM Pitch

Key Features of Momentary Tactile Push Button Switches

1. Momentary Action: The switch is only active while being pressed. Once released, the circuit opens again, making it ideal for applications where temporary activation is needed, such as in keyboards and remote controls .

2. Tactile Feedback: Users receive a perceptible click or haptic response when the switch is pressed, confirming that the action has been registered. This feedback enhances user experience, especially in devices requiring frequent input .

3. Compact Design: These switches are typically small and can be easily mounted on printed circuit boards (PCBs), making them suitable for a variety of applications, including consumer electronics, medical devices, and industrial controls .

4. Durability: Tactile switches generally have a long lifecycle due to their simple mechanical design, which involves fewer moving parts compared to other switch types. This durability makes them reliable for repeated use.

Applications

Momentary tactile push button switches are commonly found in:

• Keyboards and keypads
• Remote controls
• Game controllers
• Medical equipment
• Industrial controls
• Consumer electronics like toys and appliances.

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
