Membrane switch & Graphic overlay manufacture and exporter

Experienced and Energetic Working Team

Membrane switch factory are labor intensive. Due to spot colors on graphic overlay and mainly small or middle orders from 100-2000 pc for each item, neither digital printing nor full automatic screen printers can take the place of traditional manual or half automatic screen printers at present.
Besides printing, other processions, such as cutting, embossing, assembling are manual machine, not automatic machine.
So, producing high quality membrane switch is subject to Experienced workers, not subject to advanced machine. That is why many membrane switch factories seldom show factory tour videos at their web site.
Most workers in our factory have been working in our factory for more than 8 years, they are stable and professional, which gurentee stable and high quality
Till now, we have been exporting our products to worldwide, many foreign customers have been cooperating with us for more than 10 years. Welcome to inquiry us now!

Our printing system accepts files with CorelDraw, Adobe Illustrator or CAD with all texts curved.

Gross weight for each carton is less than 12 kgs, with package of plastic bag, bubble sheet and paper carton.

Color: quality membrane switch has bright and beautiful colors which match those on Pantone color (or PAL) card or color sample that customer offer; poor quality membrane switch has uncomfortable colors which do not match what customer appoint.
Grasping the edge of membrane switch: it is good quality if feeling stiff; it is poor quality if feeling soft.
Silver circuitry quality: after one year’s use, silver circuitry with good quality will not change; while that with poor quality will become perishing, which results in open or broken circuitry.

If you have an application for < 50000 actuations, polycarbonate is a good choice; otherwise polyester is the material of choice. Tactile keys made of polyester as overlay can be actuated over 1,000,000 times without showing signs of wear.

Sand surface diffuse light, while glossy surface reflect light parallel,  so we can read graphic overlay with sand surface easily under light  and sand surface is more popular than glossy surface.

Mistake 1: Offer Pantone Color No. C for sand surface
Customer should offer Pantone Color No. U for sand surface and Pantone Color No. C for glossy surface.

Mistake 2: Closed frame line is less than 4 mm from the outer edge off the membrane.
Printing tooling has error of +/-0.2 mm, closed frame line is difficult to be centered and is prohibited, but interrupted line can avoid the error and is permitted, as we can print interrupted lines separately.

Mistake 3: Use ZIF connector with slip clock as Interface connector.
That will damage silver circuit on the tail, the contact between ZIF connector and membrane switch’s silver tail will fail soon. That can only be used for FPC tail. correct connector please refer to https://www.sun-rising.cn/design-guide/

Mistake 4: Bending membrane switch sharply when assembling.
As LEDs are glued on screen printed flex circuit, bending may damage the contact between LEDs and circuitry and cause blind lamp; that also may cause broken metal domes inside.

Mistake 6: rip the membrane switch off the holding panel and repeat gluing
That may cause metal domes inside damaged by losing elasticity

Mistake 6: Offer Pantone color C for sand surface and offer Pantone U for glossy surface
Correct offer is that Pantone color C is for glossy surface while Pantone color U is for sand surface
