Features and Applications of Membrane Switches
Features
As we all know,the Widely Appliable Membrane Switch plays a role in transmitting instruction information in electronic products.There are many varieties of Home Appliance Membrane Switches, and their development is constantly updated with the progress of electronic products.In the 1950s,button switches, toggle switches,and changeover switches of struggling components dominated;in the 1960s,combination switches represented by key switches appeared to complete simple function conversions;with the expansion of application fields and With the increase of the function of the whole machine,the keyboard switch of conductive rubber appeared in the 1970s,and the membrane switch was a new type of electronic device researched and developed in the late 1970s and early 1980s.Intelligent,multi-functional development needs of the product.Membrane switch is a switch made by printing contact circuit with conductive paste on flexible polycarbonate or polyester film.Capacitive Touch Membrane Switch is a kind of contact switch.Membrane switch is planar, multi-layer combination, sealed structure.Widely Appliable Membrane Switch is an assembly of electronic machine control system integrating key switch,panel function mark, reading display transparent window,indicator light window and circuit.
Characteristics (1) Durability The life of a Home Appliance Membrane Switch can generally reach more than one million times. The reason for such a long life is that the action of the switch is only realized by the vertical spring of the elastic membrane. Although the elastic film has undergone millions of creeps, the creep range is very small, only 0.1~0.3mm (that is, the switch stroke), and the rationality of material selection is far from reaching the yield limit of the film. Therefore, the film material It can withstand a life of more than one million times without deformation. On the other hand, the contacts of the switch It is a vertical contact, and the wear amount is very small; while the screen-printed contact can form a sufficient thickness, and a layer of conductive carbon is printed on the silver paste contact to achieve high wear resistance and self-lubricating purposes, so the thin film The service life of the switch is dozens of times higher than that of the mechanical contact switch. (2) Good sealing performance Because the Home Appliance Membrane Switch is an integral sealing structure,the contacts of the switch are not eroded by harmful gases and are not easily oxidized; it is waterproof and dustproof,so Widely Appliable Membrane Switch is more suitable for various harsh environments.
(3) Small size, light weight and reliable structure Widely Appliable Membrane Switches can be arranged and combined into a membrane keyboard in design,and its setting density is high, and Capacitive Touch Membrane Switch is a sealed sheet structure composed of multi-layer films. Completed,the total thickness is 1~3mm,so the volume is reduced,the quality is reduced,and the reliability is improved. (4) Rich colors and beautiful appearance Capacitive Touch Membrane Switch can reflect individuality in the design of color and pattern according to the user's design concept, and reflect the comprehensive characteristics of material beauty, decoration beauty and craftsmanship beauty in decoration effect. (5) Reduce the supporting cost of electromechanical products Traditional Home Appliance Membrane Switches need to be welded and even fixed brackets are required during installation.The installation of the Capacitive Touch Membrane Switch is sticking type, as long as the adhesive paper is removed,Capacitive Touch Membrane Switch can be firmly pasted on the surface of the whole machine, and the outlet of the lead wire is inserted into the socket of the rear circuit of the whole machine,and the circuit can be connected in an instant.Save labor, ave materials,and reduce the supporting cost of the whole machine.
Application Home Appliance Membrane Switch is a non-locking switch.Suitable for switching power less than 1W, maximum working voltage: 42V (DC) or 25V (DC), and maximum working current less than 100 mA.Capacitive Touch Membrane Switch can be widely used in all microcomputers and numerical control. Many fields of intelligent instruments,meters and electronic circuits with discrimination and memory functions.
