Membrane Switches and Keypads


Membrane keyboards or membrane switches are pressure design pads that have only outlines and symbols printed on a flexible flat surface. These Membrane keyboard work by electrical contact between the keyboard surface and the underlying circuits when the key top areas are pressed with help of an external force. The basic principle behind the functionality of a membrane keypad is that the contact behind the tactile key or non - tactile key closes an open loop of the circuit which ends on the flexible tail. Membrane keyboard / keypads can range from flexible keyboard, backlit keyboard, waterproof keyboard, embossed keyboard, hybrid keyboard, front facia keyboard, tactile and non - tactile keyboard and many more.

In order to offer you the exact product as per your specs, it is recommended that you provide the following information to us Keyboard can be made with different specs depending on your application. Mainly we need three kinds of information to start a job:

Here you are requested to give dimensions of Keyboard, Display & LED locations, stud size & its location, switch size & its location, connector location and tail length and its location etc.

Here you are advised to provide a detailed circuit diagram (logic Diagram) of electronic components with component specifications including pin numbers of connector. However we recommend to provide us the freedom to select connector pin numbers so that we can minimize the cross connections and reduce the complexity and improve the reliability of the Keyboard. In case of flexible membrane Keyboard, cost of the product will reduce as well.

It is important to select proper overlay material depending upon the application. The most common and economical material is Polycarbonate. We use special grade polyester which is very suitable for embossing and gives good chemical and scratch resistance. In order to make a impressive and attractive overlay, it is important to choose proper color, shade, font size, font shape etc.

Application of the product (consumer, industrial, medical) etc.
Enclosure color
Functional characteristics of LED & Switch

You can choose a combination of matt and glossy finishes on the overlays. We can provide background illumination on selective areas of the Keyboard (Electro-Luminescent Technology).
The aesthetic look of the Keyboard can be further enhanced by embossing the switch and LED areas.

Create your next membrane switch design with us

In order to provide customer with optimal solution, it is very crucial for us to know where and how the membrane switches will be used. The most common approach we prefer is when customer provides a graphic drawing or design and a description of how and where the customer plans to connect the membrane keypad at their site. Additional information required for designing your product is mentioned below.
