Flat Flexible Three Button Membrane Switches With Four Contacts
Connector
Female connector membrane switch is a specialized type of membrane
switch that is designed to interface with a male connector with a
2.54mm (0.1 inch) pin spacing. This type of membrane switch is
commonly used in various electronic and electrical applications.
Here are the key details about this component:
Connector Specification:
The female connector part of the membrane switch has a 2.54mm (0.1
inch) pitch, which means the distance between the centers of the
connector pins is 2.54mm.
This standardized pitch size is widely used in electronic
components, circuit boards, and wiring systems, allowing for
compatibility and easy integration.
Construction:
The membrane switch consists of multiple layers, including a
graphic overlay, a spacer layer, and the conductive switch
membrane.
The female connector is integrated into the bottom layer of the
membrane switch, providing the electrical interface to the mating
male connector.
The connector can be made of various materials, such as gold-plated
copper alloy or nickel-plated steel, to ensure reliable electrical
contact and durability.
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
