Membrane switches are the part of advanced technology. The advantages of Membrane keyboards are aesthetical look, durability, environmentally safe and cost effective.
A membrane switch is a simple electrical device used to direct the flow of low voltage, low current electricity through an electrical circuit. The low current levels required by membrane switches make them particularly useful in integrated circuit applications.
Membrane switches are of two types depending upon the nature of their construction. They are constructed according to the requirement or application.
These switches use a rigid circuit board in spite of using screen printed flex circuits and help in easy addition of other components like LEDs and resistors and this can be achieved by applying a graphics layer directly onto a PCB. Standard thickness of bare PCB range from 0.4 mm to 3.2 mm and the board can be single-sided, double sided or multi layer.
A PCB allows components to be soldered directly to the board. It also provides a wider, as well as more Connector locations , depending on the complexity of the design. In built Mounting screw can be used for fixing LCD, Display PCB & Keyboards.
Our Company has special design for manufacturing these rigid membrane switches. These are prepared of excellent quality material with the use of latest technology for superb performance and durability.
Flexible membrane switches can bend, move and twist without damaging the conductor and used where flexibility is required. These switches have small size, thin thickness, light weight, shock resistant, abrasion resistant and convenient in installation and connection. It is used in ultrasound probe, medical device, industrial equipment, manufacturing equipment, aerospace industry etc. We manufacture these flexible membrane switches with latest technology and superfine material for better performance and longer life.
The membrane switch is made from layers of flexible plastic sheets bonded together with thin adhesive sheets. The electrical circuitry is created by screen printing conductive inks on the plastic layers forming traces (that act like wires) and contact pads in the key areas. After assembly, the membrane switch components form an electrical device containing one or more touch switches.
