Five product families, one production line.
Twelve product types, from flat switches to LED and metal dome panels. Every one is built to your drawing.
2 product types
Metal dome switches
Stainless steel domes for a crisp snap and millions of actuations.
2 product types
LED membrane switches
SMD chip LEDs embedded in the circuit for status indication and lighting.
2 product types
Flexible membrane circuits
Coverless flexible PET circuit layers, ready to pair with your own front panel.
2 product types
Panel labels & overlays
Screen-printed flat, embossed and luminous labels for equipment front panels.
Total stack: 5 layers
Anatomy of a membrane switch
Five layers, one touch.
A membrane switch is not a single part. It is a stack of individually produced layers, precisely aligned and laminated together.
- 1
Graphic overlay
PET or polycarbonate filmSecond-surface screen-printed outer layer, resistant to UV and chemicals. Embossing and texture are formed here.
- 2
Upper circuit
Silver conductive, flexible PETA printed film that flexes on a key press to touch the lower circuit.
- 3
Spacer
Adhesive spacer film, vent channelKeeps both circuits apart at rest. Its thickness defines key travel and feel.
- 4
Metal dome and lower circuit
Stainless steel domeThe dome collapses at a defined force, delivers a crisp snap and closes the circuit.
- 5
Rear adhesive and tail
3M acrylic, flexible connectorThe adhesive that fixes the switch to the device, plus the flex tail to your controller.
Metal dome or polyester dome?
Each gives a different touch. Press the switch and watch the dome collapse and the circuit close.

Company
Thirty years of doing one thing, better every year.
G&D Elektronik was founded in 1995 by Bahadır Gezici and Ahmet Dolmacı. Today, with five engineers and an experienced production team, we manufacture in our own 1,200 m² building.
Circuit and graphic screen printing, lamination, die cutting, embossing, connector assembly and final testing all happen under one roof. Our products are exported to many countries, led by Germany, Switzerland, Italy and Israel.
Frequently asked questions
What is a membrane switch?
A membrane switch is a thin, laminated keypad made of a screen-printed graphic overlay, a spacer layer and flexible conductive circuits. When a key is pressed, the upper and lower circuits make contact and generate a signal.
How fast can a prototype be ready?
Once the design is approved, prototype samples are usually produced within 24-48 hours. Series production typically takes 2-3 weeks depending on volume and construction.
What is the difference between metal and polyester domes?
Metal domes offer a crisper snap and a longer actuation life. Polyester domes give a softer feel and are more economical. The choice depends on usage frequency and the tactile feel you want.
Is there a minimum order quantity?
We work with low-volume samples and pilot runs. The same line scales from small batches to more than 500,000 units a year.
What do you need to prepare a quote?
A technical drawing (DXF, DWG or PDF), artwork, approximate quantities, preferred key feel and the operating environment all speed up the quote. No drawing yet? We can start from a sample or photos.
Do you manufacture for customers outside Turkey?
Yes. We export regularly to many European countries, led by Germany, Switzerland, Italy and Israel.

Membrane Switch vs. Touch Screen: How to Choose the Right HMI for Industrial and Medical Devices
For engineers designing industrial machinery or medical devices, the choice of HMI technology has profound implications for usability, durability, and long-term reliability. The primary decision often comes down to a classic matchup: the rugged dependability of a membrane switch versus the dynamic flexibility of a touch screen.
