LUNFENG membrane switches are produced to the highest standard by our skilled operators and in compliance with ISO 9001 Approval, which ensures your membranes are fully functional and to the highest standard. All membrane switches undergo 100% final test inspection to ensure error-free operation and that the buttons last as long as the machine they control.
Durable solution
We produce membranes using the same techniques we use on our durable overlays, and with sub-surface printing the membrane will endure even the harshest treatment and cleaning.
Versatile
Each membrane can be produced to a specific design and layout providing greater flexibility in size, format, materials and finishes. Combined with a range of adhesives we can ensure it easily adheres to your product.
Embossing
In many applications we emboss or hydroform the keys of a switch to meet customer requirements. ‘Pillow Embossing’, ‘Dome Emboss’, ‘Rail Embossing’ or ‘Multi-Level Emboss’ may be used depending on the finish the end membrane requires.
Tactile & Non-Tactile
The keys can be produced with either a tactile feedback which confirms activation when pressed, or with a non-tactile format for a completely flat finish for easy cleaning and maximum durability.
Pinouts
The membrane switch circuits can be produced in two formats, a common bus layout or using a matrix style format.
