How To Make A Membrane Switch？

About Membrane Switches

A membrane switch is a short-circuiting component used in normally open circuits. Because of the flexible graphic and interior layers (also known as membranes) that cover a circuit printed on PET or etched on polyimide. These switches are also known as membrane switches.

Membrane Switch Production Procedure

LuphiTouch demonstrates how to install a membrane switch rightly. You can view the whole set of instructions below.

Firstly, Stick an adhesive insulation layer on back of the internal electric circuit layer, with leaving terminal connect slip exist slot.Press it to attached to the electric circuit layer strongly

Peel off stamped adhesive liner from seperation paper, stick on the circuit layer in accurately,attentionly ,space whites for tactile domes,led piece and other electric components should be left, then roll strong by soft roller .

Feed all spaces with metal domes.Press all domes tightly by using soft roller, make them embed and adhered strongly.

tear off adhesive layer’s transfering paper slowly, without domes taken off !

Stick a transparent insulating layer on it,pressing it strongly with soft roller.Therefore ,the terminal FPC connect strips exit slots are left

All alimimation finishd , at last step, cover the top layer on it, which is graphic overlay, such this , a membrane switch installed completely

 

In comparison to basic switch designs, complex user interfaces frequently require more components, which usually results in more layers. Multi-layered switches may have integrated components like LEDs, resistors, light sensors, and even programmable chips, as well as some type of ESD, EMI, or RFD shielding. For the circuit layer, we frequently use copper flex or PCBs to support these more robust designs. The electronic alternatives are thus essentially endless. LuphiTouch is a leading membrane switch manufacturer with more than 15+ years of exporting experience. We are professional in every aspect of design and production.
