LEDs Membrane Switch Pad for Digital Stir Plate Devices
Membrane Switch Opinion
A membrane switch is a momentary electrical contact on/off switch that activates or deactivates an electric circuit. These are sometimes called single pole, single throw, normally open (SPSTNO) switches. Custom membrane switches are manufactured by screen printing the circuit directly onto a plastic substrate with silver or carbon conductive ink. The simple, versatile, durable, and economical design of a custom membrane switch makes it a superior alternative to the mechanical switch.
Membrane switches, also known as touch keyboards, membrane panels, etc., are made of soft materials such as PC, PVC, PET, FPC and double-sided tape, using screen printing technology to produce a multi-plane combination sealed set of graphics, buttons, A plastic electronic product that integrates marking and symbol display, conductivity and electronic switch functions.
The membrane switch film panel is a popular word mark and trademark that integrates decoration and functionality in recent years. Print established graphics, text descriptions, transparent windows, etc. on flexible plastic materials such as PVC, PC, PET, etc., and paste different types of double-sided tape to make plastic products used for identification and protection. The film panel has beautiful appearance, clear pictures and texts, and good airtightness.
Membrane switch mechanical properties:
Reliability service life:> 1 million times;
Closing displacement: 0.1~0.4mm (without touch) 0.4~1.0mm;
Healthy standard work force: 15~750g force;
Silver paste migration: at 55ºC, temperature 90%, after 56 hours, the second line is 10MΩ/50VDC;
No oxidation or impurities on the silver paste line;
Silver paste line width ≥ 0.3mm, minimum interval 0.3mm, line burrs <1/3, line gap <1/4 line width;
Lead spacing standard 2.54 2.50 1.27 1.25mm;
The resistance of the lead wire is d=10mm steel. The line was pressed 80 times continuously.
The transparent window of membrane switch is transparent and clean, and the color is uniform, free of scratches, pinholes, and impurities.
Membrane Switches Industrial and Consumer Applications:
Medical testing and diagnostic equipment
Any industrial manufacturing equipment with a control panel
Household appliances such as microwave ovens and stoves
Retail/consumer applications such as vending machines, kiosks, exercise equipment, and gasoline pumps
Military equipment to handle rogue treatments
Membrane Switch Components
Membrane switches have following basic layers:
Graphic overlay with subsurface printed text/graphics and a polyester or polycarbonate layer with or without embossed keys
ESD shielding layer (optional)
Spacer and/or dome retainer
Polyester printed circuit layer
Rear adhesive with liner
Membrane Switch Materials Ideas
The graphic overlay surface or faceplate material is one of the main considerations in designing a customized membrane switch, with polycarbonate and polyester being the most commonly used materials.
Polycarbonate is clearer, easier to fabricate and print but is less durable in constant use.
Polyester is more challenging in its manufacturing, however it is more durable and has better resistance to environmental conditions.
Polycarbonate is less expensive than polyester, but the difference is minimal and this is not usually a major consideration.
Kaike company membrane switch design and engineering team will guide you chose the best membrane switch product based on your needs and the conditions in which your membrane switch will be used. Hard-coated materials are also available to reduce gloss/glare and provide added durability, scratch-resistance, and chemical resistance...
