How to compared touch switch?

 

The popular saying, touch that is light touch. Then, the touch switch can also be understood as the light contact of the switch can control the on and off of the switch, that is, lightly press the switch on, release and disconnect. It has a wide range of applications and is widely used in home appliances, building automation, automotive equipment, digital audio and video, and other fields.

 

Tactile Switch SMD.jpgWe compared the following aspects of the touch switch: punching - injection - cleaning - assembly - molding - inspection and other processes; and the membrane switch process is mainly: screen printing - die cutting - assembly - - Testing and other processes. Both of them have high demands on the production environment. Relatively speaking, the use of workshops with higher levels of dustproofness guarantees the product quality. Membrane switches require high precision, require the accurate matching of the parts, and are also critical of the appearance and color of the product. The touch switch requires a higher degree of precision, because the cooperation of the parts directly affect the product description and feel, the product's performance requirements are very high, but the appearance of the product, the color is not as critical as the membrane switch. The cost and price of the tact switch are relatively low, and there is no large price adjustment due to the fluctuation of raw materials in the market. The membrane switch is relatively high in price and large in size, which is greatly affected by the price of raw materials. Both the touch switch and the membrane switch are functional switches. When the touch switch is in use, the switch can be turned on by gently pressing the switch button. When the hand is released, the switch can be disconnected. The internal structure of the touch switch is based on a metal dome. Forced movement to achieve continuity. Membrane switch is a button with its own line, usually the top layer is composed of PET or PC and other materials with a text or pattern of the panel, the lower layer is a conductive line, the middle layer is an analog switch and isolation Double-sided adhesive made of PET material, the lowest part is usually the contact and connection line on the PET material. When the user presses a key portion of the surface layer with his or her finger, the key contact is brought into contact with the corresponding portion of the contact portion of the lower layer to form a current connection.


Tactile switches are small in size and are standard parts. Sizes and related parameters must be combined with industry standards and the colors are relatively simple. Membrane switches can be ordered in different sizes, appearances and colors according to the requirements of customers. It is more convenient and flexible to use. The membrane switch has good flexibility, closed structure and waterproof structure, and has better adaptability to the environment. The tact switch cannot function independently and must be used in conjunction with a PCB circuit board to form a complete open control system. Membrane switches integrate panels, switches, and conductive circuits to form a complete control system. Can provide customers with a whole switch solution.
