Screen Printing Silver Conductive Circuit Standard Membrane Switch With 2.54MM Pitch

2.54mm pitch 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.

Customization:
The graphic overlay can be customized with custom graphics, text, and symbols to indicate the functionality of each switch area.
The size, shape, and layout of the switch areas can be designed to fit the specific requirements of the application.
The overall dimensions of the membrane switch can be tailored to match the physical constraints of the device or equipment it will be integrated into.

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
