America designed item / ZS-31 / 175mm*175mm / Metal Dome Tactile
Membrane Switch with Pins and Sheilding Layer
What Is A Membrane Switch?
Membrane switches are generally made from five different layers. This includes membrane,
graphic, tactile, rigid and static layers. The first layer contains the graphic interface for the
user to control the machine. It can also include a flexible circuit for less expensive
alternatives.
Another layer will contain the printed circuit which allows a signal to be transmitted. The ink
that is used for the printing on the circuit is generally made up of a variety of metals. This
helps for the signal to be conductive for turning on and off.
Membrane switches allow forcommunication to take place in electronic devices. Membrane
switches are a piece of equipment that can be highly sophisticated or rather simple by design.
Features:
1. Material: PET/PC with different thickness and finish
2. Button effect: embossing + metal domes respectively for good tactility and perfect
feedbacks. we can offer the other options: a. embossing, no metal domes.
3. metal domes, no embossing.
4. no embossing, no metal domes (flat type)
5. LCD clear window can be made.
6. Colors for graphics are matched with Pantone No., Bi-color leds are also available.
