Customizable Surface Mount Membrane Panel Switches For Hairfoil Device
Key Features of Membrane Panel Switches
-
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 .
-
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 .
-
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 .
-
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
