Custom Membrane Switches
A custom membrane switch combines a printed graphic overlay, spacer, circuit layer, adhesive, tail, and connector into a low-profile control interface. It is useful whe...
Membrane Switch Products for Custom Control Panels
Use this product map to choose the correct interface construction before you send a drawing. The right choice depends on enclosure space, expected life cycle, sealing, illumination, tactile feel, and connector routing.

Membrane Keypads
A membrane keypad is a membrane switch layout where the user experience depends heavily on key spacing, embossing, tactile feedback, and legend durability. It is not ju...
Graphic Overlays
A graphic overlay is the user-facing layer of a control panel. It carries legends, colors, windows, icons, dead-front graphics, texture, and protective film performance...
Silicone Rubber Keypads
A silicone rubber keypad gives a soft molded key feel and can integrate conductive carbon pills, coatings, laser-etched legends, and backlighting. It is often chosen wh...
Capacitive Touch Panels
A capacitive touch panel is useful when the product needs a smooth sealed surface, no moving keys, and a modern HMI feel. It is less forgiving than a basic membrane swi...
HMI Assemblies
An HMI assembly combines the visible interface and the electrical switching or touch structure. It can include overlay, membrane circuit, LED windows, rubber keypad, di...
Waterproof Membrane Switches
A waterproof membrane switch is not waterproof because the top film looks sealed. The weak points are usually tail exit, adhesive edge, connector area, vent path, enclo...
Backlit Membrane Switches
Backlighting can improve night use and status visibility, but it adds stack height, electrical routing, optical control, and testing risk. The right method depends on b...
Tactile Membrane Switches
A tactile membrane switch uses metal domes or formed structures to give a snap feel. It helps operators know that a key has actuated, but the dome choice must match the...
PCB and FPC Membrane Switch Assemblies
PCB and FPC membrane switch assemblies are used when a simple printed silver circuit is not enough. They can support components, tighter connector requirements, LEDs, s...

How to choose the first direction
Start from the operating environment and enclosure. The product name can change after review, but tail route, sealing, and user feel are harder to rescue late.
- sealed flat panel: membrane switch
- raised key feel: membrane keypad or silicone keypad
- clear printed face: graphic overlay
- smooth no-button control: capacitive touch panel
- ready-to-install interface: HMI assembly

What to send for RFQ
drawing or outline dimensions
overlay material preference
circuit or pinout requirement
tail length and connector type
annual and sample quantity
operating environment and IP target
sample deadline
RFQ support
Send a drawing before the design is locked.
For your membrane switch project, the useful review happens before tail exit, connector, adhesive, and artwork decisions become expensive to change.
