New Information

The overall performance of the membrane switch can be summarized as

From:admin Date: 2019-01-14
The membrane switch is a switch made of a conductive paste printed contact circuit on a flexible polycarbonate or a polyester film, and is a type of a contact switch. The membrane switch is a flat type, multi-layer combination, sealed structure, and is an assembly of an electronic whole machine operating system integrating a key switch, a panel function mark, a reading display transparent window, an indicator window hole and a circuit.
1. Good sealing performance
Since the membrane switch is an integral sealing structure, the contacts of the switch are not eroded by harmful gases and are not easily oxidized; and are waterproof and dustproof, which is more suitable for various harsh environments.
2. Rich colors and beautiful appearance
The membrane switch can be personalized according to the user's design concept, and the design of the color pattern is embodied. The decorative effect reflects the comprehensive characteristics of material beauty, decorative beauty and craft beauty.
3. Small size, light weight and reliable structure
The membrane switch can be designed and arranged into a membrane keyboard, which has a high density of setting, and it is a sealed sheet structure composed of a plurality of layers of films, and the connecting lines and the lead wires between all the switches are screen printed at one time. Completed, the total thickness is 1~3mm, thus reducing the volume, reducing the quality and improving the reliability.
4. Reduce the supporting cost of mechanical and electrical products
The traditional mechanical switch needs to be welded during installation, even with the fixing bracket; the membrane switch is installed in the adhesive type. As long as the adhesive paper is removed, it can be firmly attached to the surface of the machine, and the lead outlet is inserted into the whole machine. On the socket of the rear circuit, the circuit can be turned on instantaneously.
5. Durability
The life of a membrane switch can generally reach more than one million times. The reason for this long life is that the action of the switch is only achieved by the vertical movement of the elastic film; although the elastic film has undergone millions of peristalsis, it is due to creep. The variation is small, only 0.1~0.3mm (both switching stroke), and the rationality of material selection is far from the yield limit of the film, so the film material can withstand more than one million life without deformation; On the other hand, the contacts of the switch are in vertical contact with very little wear; the screen printed contacts can be formed to a sufficient thickness and a layer of conductive carbon is printed on the silver paste contacts to achieve a high Wear-resistant, self-lubricating, so the life of the membrane switch is more than ten times higher than the mechanical contact switch.
