The light touch switch mainly includes: stamping--injection--cleaning--assembly--forming--inspection and the like; and the membrane switch process is mainly: silk screen--die-cut--assembly--detection process.
Both of them have high requirements on the production environment. Relatively speaking, the higher the dustproof level, the more reliable the product quality is. The membrane switch requires high precision, requires precise matching of various parts, and is also very picky about the appearance and color of the product. The touch switch requires a higher degree of precision, because the cooperation of each part directly affects the product description and feel, and the performance requirements of the product are very high, but the appearance and color of the product are not as picky as the membrane switch.
The light-touch switch has a relatively low cost and price, and does not cause large price adjustment due to fluctuations in raw materials in the market; while the membrane switch is relatively expensive and bulky, and is greatly affected by raw material price factors.
The light touch switch and the membrane switch are both functional switches. When the touch switch is used, the switch can be turned on by gently pressing the switch button. When the hand is released, the switch can be disconnected, and the internal structure is relied on. The metal shrapnel is forced to open and break.
The membrane switch is a kind of button with its own line. Usually, the upper layer is a panel with text or pattern composed of PET or PC, the lower layer is an electrically conductive circuit, and the middle layer is an analog switch form and is isolated. The double-sided adhesive made of PET material, the lower part is usually the contact and connecting line on the PET material.
When the button portion of the surface layer is pressed with a finger, the button contact contacts the corresponding portion of the contact portion of the lower layer to form a current connection.
The touch switch is small in size and is a standard part. The size and related parameters must be combined with industry standards and the color is relatively simple. The membrane switch can be customized according to customer requirements, and 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 independently generate functions, and must be used together with the PCB circuit board to form a complete open control system; and the membrane switch integrates the panel, the switch and the conductive circuit to form a complete control system independently. Can provide customers with a holistic switching solution.
