Smart Electronics Power Built-in Customisable Membrane Switches Panel
Membrane Switch and Keypad Services Information
Kaike membrane switches and keypad services fabricate assemblies using flexible membranes, domed or flat switch profiles, tactile and non-tactile switches and panels. Our product capabilities of membrane switch and keypad services include numerical keypads, graphical keypads, control panels, and membrane switch overlays.
Numerical keypads include numeric or alphanumeric switches and keypads for data entry, operation of menu-driven software, entry of word commands, etc.
Graphical keypads are image or graphic-based keypads for machine or process navigation and operation. Graphics should conform to international standards or be customized to the application. Common graphics have arrows, pictorials of machine operations or processes...
Control panels include full function panels for monitoring and control of machine, process, system variables and commands... They also include inputs, outputs, and interfaces tailored to the application.
Membrane switch overlays are graphical or alphanumeric coverings for keypads indicating keys or switch functions.
Polyester, polycarbonate and polyurethane typically make up the components of a membrane switch panel.
Internally, the switching mechanisms are via metal domes or conductive shorting pads.
Further enhancements include surface mount LEDs, water clear widows, dead fronts, back-lighting with optic fibre or electroluminescence and solid mounting plates.
Terminations to the PCB can be via Berg connectors and Nicomatic connectors or designed to fit Zif connectors.
Membrane switches and keypads are a fully customisable solutions for Human – Machine Interface (HMI) requirements.
Materials
Materials of construction for membrane switch and keypad services include polyester, polycarbonate, rubber or silicone, and metal...
Features
Features include backlit switches, LED indicators, outdoor environment, hazardous environment, vandal proof, washdown capable, EMI/RFI protection, ESD protection, and embossed switches.
Switches or keys are backlit for use in dark or inconsistently illuminated environments. Backlighting is frequently accomplished with an electroluminescent panel in the keypad or panel.
Switch, or operation, status can be indicated by light emitting diodes (LEDs) incorporated into the keypad. Possible uses include signifying operation, process status, verification of system functions, machine interlocks, alarm conditions, etc.
Switch keypad, or panel can be designed for outdoor use and often involves special sealing and resistance to water, sunlight, and temperature variations. Hazardous environment switches need special materials and sealing considerations for use near chemical, very high temperature, areas where fire or explosion are possible, etc.
Vandal-proof keypad, or panel casings, are resistant to unauthorized tampering, access, disassembly..
Some switches are designed for full washdown; may include materials immune to degradation by detergent, robust sealing features, etc.
Some switches can measure for protection against electromagnetic interference (EMI) and radio frequency interference (RFI) including shielding and grounding of electronics and electrical circuits and conductors. This is often required for regulatory compliance certifications.
Protection against electrostatic discharge (ESD) may be accomplished with static-dissipative or conductive elements in the switch material, special electronics grounding practices...
Embossed switches have graphics or alphanumerical characters that are raised or embossed from the switch surface.
Applications
Membrane switch and keypad services are important in many different industries. These include aircraft or aerospace, automotive, building controls, communications and electronics, financial services, manufacturing or automation, medical, retail, and security and identification. Kaike capabilities include graphical design and layout, PCB design and layout, just-in-time delivery, samples or short runs, life cycle testing, and screen printing...
