Customizable Surface Mount Membrane Panel Switches For Hairfoil Device

Key Features of Membrane Panel Switches

1. Construction: Membrane switches are typically made up of multiple layers, including a graphic overlay, circuit layers, and a spacer layer. The top layer often features printed graphics that indicate the function of each button .

2. Types:

   • Tactile Membrane Switches: Provide a tactile response when pressed, which is useful for users with visual or auditory impairments .
   • Non-Tactile Membrane Switches: Do not provide tactile feedback and often rely on visual or auditory cues to indicate activation .
   • Backlit Membrane Switches: Incorporate lighting to enhance visibility and aesthetics, using technologies like LEDs or electroluminescent lamps .
   • Capacitive Touch Switches: Use capacitive sensors to detect touch, offering a more durable alternative to traditional pressure-based switches .

3. Advantages:

   • Sealed and Waterproof: Many membrane switches are designed to be completely sealed, making them easy to clean and resistant to moisture and contaminants.
   • Low Profile: Their thin design saves space in product design and eliminates crevices that can trap dirt .
   • Cost-Effective: Generally less expensive than mechanical switches and rubber keypads, making them a popular choice for manufacturers .
   • Customizable Graphics: The surface can be printed with high-quality graphics, allowing for versatile design options .

4. Applications: Membrane switches are widely used across various industries, including:

   • Medical electronics
   • Consumer products
   • Industrial controls
   • Telecommunications devices
   • Fitness equipment

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
