DLTMS0015 is a kind of switch used on electric toothbrush products for worldmarket. The top layer is the soft silicone rubber front layer with very good tactile feeling. Due to the toothbrush usually will be contacted with water, so the reliability is very important, then for this switch used the copperflex FPC circuit and 3M adhesives. The tactile metal domes used in this switch are also gold plated ones which also can enhance its reliability.

Membrane Switch is a kind of interface operation product. Many devices, equipments, instrumens etc. need the operation interface panel. To design different symbols, diffeent colors can give users a friendly interface window and can design the circuit layer. Use metal domes contact the conductive pads on circuit laer then can get your wanted function when you press relevant buttons. LUPHITOUCH certified by ISO9001:2008 can design and manufacture various kinds of membrane keypads to meet your requirement. In addition we also have our own PCBA factory can provide one stop solution service for your projects.

PRODUCTION DESCRIPTION

> Construction:
A membrane switch typically has 6 or more or less layers. The top layer of a membrane switch is the graphic overlay interface between the user and the machine. The other critical layer is a the circuit layer. It can also be PET, FPC or PCB. All the layers are normally assembled using pressure-sensitive adhesives. Contact between two traces can be made through a printed shorting pad or through a metal dome that stands on legs.

> Membrane Keypad Structure
1) 4 layers structure: Graphic overlay + Spacer + Circuit(can be PET circuit or FPC circuit) + Back Adhesive
2) 6 layers structure: Graphic overlay + Spacer: Dome Retainer + Spacer + Circuit(can be PET circuit or FPC circuit) + Back Adhesive;
3) Other Structure
3.1) Overlay + Rubber Adhesive + Rubber Keypad + Rubber Adhesive + Retainer + Spacer + Circuit + Back Adhesive;
3.2) Overlay + Spacer + Retainer + PCB Circuit;
And also there are many other kinds of structures for the interface keypads structure. It based on customer's real needs and we can design the suitable and economical structure for our customer's final application.
