Electronic Reverse Printing Custom Tactile Dome Switch With High Performance

How Tactile Dome Switches Work

• Mechanism: The switch consists of a dome-shaped metal component that rests against a circuit board. When the dome is pressed, it collapses and makes contact with a secondary pathway on the circuit board, closing the circuit and sending an electrical signal to the device .
• Feedback: The design allows for a crisp tactile feel, letting users know that the button has been successfully pressed .

Types of Tactile Dome Switches

There are several types of tactile dome switches, each with unique characteristics:

1. Four-Legged Domes: Commonly used, these provide high actuation forces and are highly customizable.
2. Round Domes: Ideal for low-profile applications, offering a softer tactile feedback.
3. Triangle Domes: Suitable for limited circuit board space, providing high actuation forces relative to their size.
4. Oblong Domes: Designed for long narrow spaces, allowing for a full-hand squeeze.
5. SMT Domes: Surface-mount technology domes that integrate directly into circuit boards without affecting performance .

Advantages

• Durability: Many tactile dome switches, such as those from Snaptron, can exceed five million life cycles, making them highly reliable for long-term use .
• Versatility: They can be customized for various applications, including different actuation forces, heights, and tactile feedback requirements .
• Cost-Effectiveness: Tactile switches generally have fewer moving parts compared to other mechanical switches, which can lead to lower costs and longer lifespans .

Applications

Tactile dome switches are widely used in:

• Keyboards and keypads
• Medical devices
• Consumer electronics
• Aerospace and aviation controls
• Communication devices .

LED membrane switch descriptions:

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

Polycarbonate

2.More cost-effective 3.For internal and external use

2) Embossing--rim embossing pillow embossing dim embpssing

Graphic overlays can be embossed in order to insert domes (tactile), leave space for mechanical keys and provide tactile indications Pedestal embossing

3)Windows ----for display function

1. print colors windows

2.transparent finishes windows

4)Keys/buttons

Tactile keys---with metal dome or poly dome

Non-tactile--silver printing spot

5) Embeded LEDs-

miniature LED, LED colors:white, yellow, orange, green, red, etc.

6)Cable

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 or acrylic
