Membrane switches are different from traditional mechanical switches. They do not have high requirements on the layout of the casing. They do not need to drill many holes in the casing and are simple and convenient to install. The surface of the membrane switch is a printed panel, which can be printed with PC or PET. The material has a glossy surface and a matte surface. It is commonly made of raw materials imported from Autotex in the UK. The membrane switch has a beautiful appearance, with an embedded metal shrapnel installed in the middle, and a single or multi-layer silver paste circuit at the bottom. The membrane switch keys have low resistance, good pressing feel, and long service life. The high-performance 3M double-sided tape underneath can be directly attached to the product casing. Membrane switches are scratch-resistant, wear-resistant, waterproof, fireproof, dustproof, and resistant to harmful gas erosion. It is widely used in household appliances, office equipment, instruments, machine tools, medical equipment, electromechanical products, industrial controls, toys and other complete products.
Membrane switch control components on the medical bed. Printed with imported PET raw materials, the surface is fine-grained and matte and feels comfortable to the touch. It has round flat-top protruding buttons, red, green and yellow SMD LED indicators, and a high-performance waterproof structure design.

Membrane switches on medical equipment for blind people. It has comprehensive functions and simple surface color design, but there is a raised edge around the buttons. The design is exquisite and the touch is clear, so that people with low vision can easily identify the product button functions.
There are various types of membrane switches on medical equipment, including flat non-tactile type, film convex tactile type, convex frame non-tactile type, convex frame tactile type, panel concave tactile type, metal spring type, etc. These membrane switches have moisture-proof, long service life, waterproof, dust-proof, oil-proof, and no harmful gases erosion. They are light in weight, small in size, long in service life, easy to assemble and connect, and the panel can be washed without damage to the characters. The colors are rich and beautiful.
In addition, the membrane switch has good sealing performance, rigorous structure, beautiful appearance, stable and reliable performance, easy assembly and connection, washable panel without damage to the characters, etc.
Specifically, the flat non-tactile membrane switch has a long service life but no tactile feedback; the film convex tactile type has good tactile feedback but a short service life; the convex frame non-tactile type has a beautiful appearance and strong stereoscopic feeling but no tactile feedback; the convex frame tactile type has a beautiful appearance and strong stereoscopic feeling and good tactile feedback; the panel concave tactile type has no two-stage phenomenon and less structural layers, which is economical. If the panel is broken, the electrical performance will not exist; the metal spring type has good elasticity and conductivity.
The application of membrane switches in medical equipment is very extensive. For example, PVC film switches for medical equipment include PC film panel switches, control panel surface film panel switches, intelligent PC button panel touch buttons and stickers.
In summary, there are various types of membrane switches on medical equipment with various characteristics that are widely used in various fields.
Matte anti-scratch panel, metal shrapnel buttons, spherical raised buttons, orange translucent LED indicator window, 2.54mm FPC pin female connector.
The panel base material of Autotex imported from the UK has a fine sand matte surface and high-end texture. The button dome is naturally raised. The LED and metal dome switches are separated by a double-layer FPC flexible circuit board and the output is dual FPC connectors.
Medical communication equipment membrane switch telephone panel. The surface is made of anti-bacterial coating, which can effectively prevent the growth of bacteria, and there are long metal shrapnel buttons inside. There are bumps with a special feel (number 5).
Rechan Electronic Technology Co., Ltd. is a manufacturer of membrane switches and touch switches. We have comprehensive membrane switch knowledge, high-quality production conditions, and can design membrane switches for you free of charge. The membrane panel cooperates with the capacitive touch sensing circuit to form a touch sensing membrane switch. The touch switch is sensitive and can trigger the switch function as long as your finger touches the switch surface. Because the surface of the touch switch is a screen-printed PC or PMMA panel, the surface is smooth and bright, making it more beautiful than ordinary key switches. kevin@rechan.com
