What are the differences between Membrane Switch and touch switch

Due to the breakthrough in technical materials, membrane switches have made great progress in the markets of waterproof, insurance and reliable performance. Also because of its convenient installation and the decline of profit, membrane switch has gradually begun to replace the application field without touch switch. What about the difference between membrane switch and touch switch? Let's explain it to you.

The volume of light touch switch is small, which is a standard part. The measurement and related parameters must be standardized by the joint enterprise, and there are many colors; The membrane switch can be customized according to the owner's requirements, with unique size, appearance and color. It is more convenient and sensitive to use. The membrane switch has good hardness, open structure and waterproof structure, and has better adaptability to conditions.
The cost and price of touch switch are lower than planned, and there is no large price adjustment due to the stability of raw materials in the market; Compared with the membrane switch, the price is high and the volume is large, which is greatly affected by the price of raw materials.
Both the light touch switch and the membrane switch belong to functional switches. When the light touch switch is used, the switch can be turned on by quietly pressing the switch button. When the hand is released, the switch can be turned off. Its internal structure is realized by the force bouncing of metal shrapnel.
Membrane switch is a key with its own leading line. Generally, the top layer is a panel with words or patterns composed of materials such as pet or PC, the lower layer is a thermally conductive line, the central layer is a double-sided adhesive made of PET data that imitates the switching mode and plays an isolation role, and the bottom part is generally the contact and receiving line on PET material. When pressing the key position on the surface layer with the finger, the key contact shall be in position contact with the contact on the upper layer to form a DC connection.
The rise of membrane switch is quite professional. In fact, the simple one is the panel type button. This name is relatively familiar. The control panels of many facilities use membrane switches, which are widely used in the fields of electronic communication, electronic measurement instruments, light industry, medical facilities, public cars, light industry, intelligent toys, household appliances and so on.
Membrane switch is a multi-layer structure (three-dimensional) type (non locking) key switch composed of insulating data layer with definite inertia. It integrates the functions of keys, instruction parts, instrument panel and so on.
Membrane switch has the characteristics of beautiful appearance, long service life, simple structure, convenient installation, good hand feeling and small occupied area. It is widely used in all walks of life, from household appliances to high-tech products. It has gradually replaced some light touch switches in the market and is holding a great share in the market.
The basic task principle of the film is as follows: when the back plate is not pressed, the film switch is in the general form, its upper and lower contacts are disconnected, and the isolation layer acts as an isolation for the upper and lower lines.
When the membrane plate is pressed, the contact of the upper channel deforms downward and reconnects with the lower route to make the route conductive. The conductive route gives signals to the internal connecting instruments, so as to complete its echoing performance. When the finger is grasped, the upper path contact pops up and returns, the path is cut off, and the circuit triggers a one-degree signal.
