What is the difference between membrane switch and touch switch

We compare the light touch switch from the following aspects: stamping - injection molding - cleaning - assembly - molding - inspection and other processes; The membrane switch process mainly includes: silk screen - die cutting - assembly - detection and other processes. Both of them have high requirements on the production environment. Relatively speaking, the higher the dustproof level is, the better the product quality will be. The membrane switch requires high precision, precise matching of all parts, and is also very picky about the appearance and color of the product. The light touch switch requires a higher degree of precision, because the coordination of various parts directly affects the product performance and feel. The requirements on product performance are very high, but the appearance and color of the product are not as picky as membrane switches.

The cost and price of the touch switch are relatively low, and there is no large price adjustment due to the fluctuation of market raw materials; The membrane switch is relatively expensive and bulky, which is greatly affected by the price of raw materials. Both the light touch switch and the membrane switch are functional switches. The light touch switch can be connected by gently pressing the switch button when in use, and can be disconnected when the hand is released. The internal structure of the light touch switch is realized by the spring of the metal spring under the force.

Membrane switch is a kind of button with its own line. Usually, the top layer is a panel with characters or patterns composed of PET or PC materials, the lower layer is a conductive line, the middle layer is a double-sided adhesive tape made of PET materials that simulates the switch form and plays an isolation role, and the bottom layer is usually the upper contact and connecting line of PET materials. When pressing the key part of the surface layer with your finger, the key contact contacts the corresponding part of the contact of the lower layer to form a current connection.

Light touch switch is a standard part with small volume. Its size and relevant parameters must be in accordance with industry standards, and its color is relatively simple; The membrane switch can be customized in different sizes, appearances and colors according to the requirements of customers, making it more convenient and flexible to use. Membrane switch has good flexibility, closed structure and waterproof structure, and better adaptability to the environment. Touching the switch can not generate functions independently. It must be used together with PCB to form a complete open control system; The membrane switch integrates the panel, switch and conductive circuit to form a complete control system independently, which can provide customers with an overall switch solution.
