Custom Membrane Keypad Manufacturer for Germany – Key Automation
Key Automation manufactures and exports custom membrane keypads (German: kundenspezifische Folientastaturen and Membranschalter) for customers in Germany. A membrane keypad is the interface between people and machines. Ours are built from high-quality polyester (PET) and polycarbonate (PC), with printed circuits that register every key press.
Thanks to their flexibility and easy mounting, custom membrane keypads are used in consumer electronics, industrial automation and medical equipment. Below you will find the available types, technical specifications, materials, features and applications.
Types of Custom Membrane Keypads We Supply to Germany
We design and manufacture custom membrane switches to your drawing, from the first prototype to series production. The main types are:
- Tactile Membrane Keypads: The most common type, with a metal dome, polydome or embossed key under each key position for a clear click. Legends and symbols are printed on the overlay, and the circuit traces are printed with silver or carbon ink. Stainless-steel domes, polydomes and hydroformed (embossed) keys are all possible.
- Non-Tactile Membrane Keypads: A flexible membrane switch without metal domes, used where low noise and smooth operation matter. In a non-tactile membrane keypad, the underside of the overlay carries printed conductive pads, so the switch closes without a snap action.
- Backlit Membrane Keypads: LEDs or fibre optics under the keys make the legends readable in low light. Backlit keypads are widely used in automotive, aerospace and defence applications and in machines that are operated in dim environments.
- Capacitive Membrane Keypads: A touch-sensitive design that reacts when the user touches the sensor area. It suits modern devices that need a smooth, easy-to-clean front without moving parts.

Raw Materials Used
The quality of a membrane keypad depends on its materials. For stable performance in industrial use we work with:
- Polyester (PET): Highly durable and commonly used for the top layer and the circuit layers of flexible membrane switches.
- Polycarbonate (PC): Tough and clear, which makes it a good choice for graphic overlays and printed windows.
- Adhesives: High-quality adhesives such as 3M and Avery Dennison for a secure bond between the layers.
- Silver Ink: Used in the circuit layers for conductive traces.
- Carbon Ink: A cost-effective option for conductive traces and crossovers.
- LEDs: High-quality LEDs for backlit membrane keypads.
Features and Benefits of Our Custom Membrane Switches
Our custom membrane keypads combine robust materials with options that can be adapted to your product:
- Multi-Functional Integration: Besides standard keys, we can integrate touch-sensitive areas, haptic feedback and proximity sensors. Haptic feedback creates a vibration that feels like a mechanical button, and a proximity sensor can wake up the keypad or the whole system when a hand approaches.
- Durability Enhancements: Our custom membrane keyboards and keypads can be fitted with UV-resistant and waterproof layers that protect the printed graphics. A special coating also protects against solvents, oil and abrasion in industrial use, and the keypads can work in both cold and hot environments.
- Connectivity and Interface Options: Our custom membrane switch prototypes can be combined with wireless modules such as Wi-Fi or Bluetooth, which is useful for remote-controlled devices. Standard interfaces such as ZIF and FFC connectors are available to match your electronics.

Custom Membrane Switches for German OEMs
German OEMs usually need a partner who can work from a drawing, document every material and deliver on time. We support the full project, from design review to export.
- Design review: We check layout, graphic overlay, circuit design and connector against your drawing before tooling starts.
- Prototype: A custom membrane switch prototype can be produced for fit and function tests.
- Protection level: Protection levels of IP65 to IP67 are possible, as shown in the specification table, for devices exposed to dust and water.
- Delivery: Export shipments to Germany by air or sea freight, with the Incoterms agreed in advance.
As a custom membrane keypad manufacturer for the German market, Key Automation is committed to improving industrial keypads with robust, well-engineered membrane switches. Contact us today for more information, a prototype or a quotation.
Custom Membrane Keypads for Germany: Frequently Asked Questions
A custom membrane keypad (membrane switch) is a thin, flexible input panel made from layers of polyester or polycarbonate with a printed graphic overlay and printed circuits. It is designed to your drawing, so layout, colours, feedback and connector match your product exactly.
Yes. Key Automation designs and manufactures custom membrane keypads in India and exports them to customers in Germany, from prototypes to series production.
Tactile keypads have a metal dome or embossed key that gives a click. Typical actuation force is 150 g to 500 g and the life expectancy is about 1 million actuations per key. Non-tactile keypads have no snap action, need 100 g to 300 g and are rated for about 5 million actuations per key.
Overlays are made from polyester (PET) or polycarbonate (PC) with acrylic or silicone adhesive. Circuits are printed with silver or carbon ink, and backlit versions use LEDs or fibre optics.
According to our specification, protection levels from IP65 to IP67 are possible for all four keypad types. The required level should be agreed when you send your enquiry.
Yes. LED and fibre-optic backlighting are available, with customisable LED colours such as red, green and blue. Backlit keypads are useful in low-light and outdoor equipment.
A prototype can be produced so that your team can test fit, key feel and function. Send your drawing or sample and we will confirm the process and the timing.
