Know what are Membrane Keypads and Its Advantages:

Posted by markwahl barg on March 23rd, 2019

A membrane keypad is a flexible keyboard which is permanently operational even under special conditions of use. It consists of several individual sheets which are superimposed.

Due to the extraordinary variety of design options, membrane keyboards are used in almost every type of electronic device and medical device manufacturers. The ergonomic and design requirements are virtually unlimited.

Membrane keyboards are e.g. used where their dirt and water resistance or their easy cleanability are required. You will also be used if you want a compact design or a small number of pieces because of comparatively low tooling costs.

You can choose from a variety of constructions of varying tactility and a wide range of viewing windows, screen panels, and lighting options.

In many applications, tactile and acoustic feedback is desired. Here, the embossing of the cover foil and the use of metal snap-on discs are ideal for giving the user strong feedback. In return, it is also possible for sensitive environments to realize a virtually silent execution.

Advantages of membrane keyboards:

• Lightweight, space saving.
• Printing the back of the film for a robust, individual design.
• Individual tactility.
• Dustproof and water-resistant, resistant to chemicals (solvents).
• Easy to clean.
• Long service life (over 1 million operations).
• EMC shielding possible.

Custom Membrane Switches:

All design ideas can be realized with membrane keyboards almost limitlessly. Rigid or flexible - depending on the application, membrane keyboards can offer just the features you want. Membrane keyboards with pressure point ensure a reliable, low-rebound switching behavior, regardless of the type of key operation. The shape of the contact spring guarantees secure contact with clear feedback.

Highest reliability requirements for virtually zero-current circuits can be met by double-sided contact gold plating for rigid designs with printed circuit boards.

For country-specific inscriptions, membrane keypad with subsequently exchangeable insertion strips is available. In an instant, existing keyboards can be adapted to the respective labeling variant. Of course, the lifespan is also well over 1 million operations guaranteed.

Why you should go with custom membrane switches?

• Have no restrictions in the application and specific properties.
• Open up new dimensions in design with full functionality.
• Have proven themselves in highly sensitive, safety-relevant areas such as medical and nuclear engineering.
• Cannot be surpassed with well over 1 million operations in reliability and service life.
• Enable ergonomically optimal work.
• Are intelligent, compact, powerful, safe to use, service-friendly and tactile pleasant.
