We manufacturer and supply a wide range of custom membrane keypads fabricate assemblies using flexible membranes, domed or flat switch profiles, and tactile and non-tactile switches and panels. Product capabilities of our membrane switches and keypad services can include numerical keypads, graphical keypads, control panels, and membrane switch overlays.

Custom Membrane Switches

Our 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 may conform to international standards or be customized to the application. Common graphics include arrows, pictorials of machine operations or processes, etc. Control panels include full function panels for monitoring and control of machine, process, or system variables and commands. May include inputs, outputs, and interfaces tailored to the application. Membrane switches overlays are graphical or alphanumeric covering for keypads indicating key or switch functions.

Materials of construction for membrane switch and keypad services include polyester, polycarbonate, rubber or silicone, and metal. Some suppliers provide texturing such as pebbling, knurling, ridges or other texturing for aesthetic or operator tactile identification purposes. Features include backlit switches, LED indicators, outdoor environment, hazardous environment, vandal proof, washdown capable, EMI / RFI protection, ESD protection, and embossed membrane 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 (e.g., red = stop, green = go), process status, verification of system functions, machine interlocks, alarm conditions, etc. Switch, keypad or panel can be designed for outdoor use; often involves special sealing and resistance to water, sunlight, and temperature variations. Hazardous environment membrane 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, etc. Some switches are designed for full washdown; may include materials immune to degradation by detergent, robust sealing features, etc.
