CUSTOM MEMBRANE SWITCH

STRUCTURE

The membrane switch is an operating system which integrates key function, indicating element and instrument panel.  It consists of four parts: panel, upper circuit, isolation layer and lower circuit. Press the membrane switch, the contact of the upper circuit deforms downward, and the contact of the plate of the lower circuit is conductive. After the finger is released, the contact of the upper circuit bounces back, the circuit is disconnected, and the loop triggers a signal. Membrane switch has rigorous structure, good appearance and sealing performance.  It has the characteristics of waterproof and long service life.  
 

Application 
Widely used in user interface of electronic communication, electronic measurement instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances and other fields.

Process Flow

FQA
Q1.  Do you provide free samples?
A1.  We can provide samples and charge freight free of charge.
If you have any special membrane switch sample, please contact us for more details.

Q2.  Can the product be produced according to customer requirements?
A2.  We can customize according to the required specifications and drawings of membrane panels.

Q3.  Is it allowed to visit the factory?
A3.  Yes, we always welcome customers to visit our factory at any time.

Q4.  How to solve the faults of the products during using?
A4.  Please email us about the problem by pictures or videos of the membrane overlays. We will check the problem and offer solution during 24 hours

Q5.  Where is your factory?
A5.  We're a source membrane switch manufacturer, our workshop locates in 5th floor, Building 96, HuLi Park, Xiamen, China.

Q6.  What is screen printing?
A6.  Screen printing, also known as silk screening, is a printing technique where a mesh screen is used to transfer ink onto a substrate, such as fabric, paper, metal, or plastic. The process involves creating a stencil (or "screen") of the desired design on the screen mesh, which is typically made of polyester or other fine materials. The areas of the screen that are not part of the stencil are blocked off, so that when ink is pressed through the screen using a squeegee, it only transfers onto the substrate in the open areas of the stencil, creating the desired image.

Q7.  Can the color of the membrane switch overlay product be customized?
A7.  Our colors can be customized according to PMS ( Pantone matching system by usual) .

Q8.  Can the membrane switch be equipped with LED lights?
A8.  Yes. Generally, there are monochrome lamps, two-color lamps and three-color lamps available. Please contact us for specific requirements.

Q9.  What is the thickness of the membrane switch control panel?
A9.  Generally 0.9 ~ 1.3mm. And we support customized thickness if it's in need.

Q10.  What are the types of convex keys on the membrane switch panel?
A10.  Including round, pan, convex edge, convex key shape, no convex, etc. Please contact us for specific requirements.

Q11.  How many layers can the membrane switch be customized?
A11.  The general design is 6 layers, but can be customized according to special requirements.

Q12.  What is the distance between the tail wires of the membrane switch?
A12.  Generally 2.54mm, but there are other specifications of 1mm lamps. Please contact us for specific requirements.

Q13.  Do I need to provide drawings?
A13.  Yes, we need you provide high resolution drawings in vector format like PDF CDR or AI file, etc. In addition, need you provide the circuit drawing at the same time.
