Custom Waterproof Flexible Membrane Switch Keyboard for Instrument and Equipment

Product Description

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. Widely used in electronic communication, electronic measurement instruments, industrial control, medical equipment, automobile industry, intelligent toys, household appliances and other fields.

Q5. Where is your factory?
A5. Our factory address is: 4th floor, No. 308, Tong'an Park, Tong'an Industrial Zone, Xiamen, China.

Q6. What is the quality level of your products?
A6. We have CE, ISO and other certificates.

Q7. What is screen printing?
A7. Screen printing refers to making a screen printing plate with pictures and texts by using the screen as the plate base and the photosensitive plate making method. Using the screen printing plate, the holes in the pictures and texts can pass through the ink, and the holes in the non pictures and texts can not pass through the ink
It can print through the basic principle of ink. When printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part of the screen printing plate with a scraper, and move towards the other end of the screen printing plate at the same time
Moving at a uniform speed, the ink is squeezed by the scraper from the mesh of the graphic part to the substrate, so as to produce the graphic design required by the customer.
Its advantages are:

1. not limited by the size and shape of the substrate
2. Strong optical rotation resistance
3. The layout is soft and the printing pressure is small
4. Flexible printing methods
5. Strong ink layer coverage
6. Strong adhesion
7. Suitable for various types of inks
8. Suitable for long-term display and expressive advertising outdoors
