How application risk changes the design
A medical keypad, a vending keypad, and an outdoor pool control may all be membrane switches, but they should not use the same material assumptions. Cleaning, UV, water, glove use, public abrasion, and enclosure surface change the stack.
- PET and polycarbonate graphic overlays
- printed silver or carbon circuit layers
- metal dome and embossed key design
- LED windows, light guides, and dead-front icons
- adhesive stack selection for enclosures
- FPC, PCB, and connector integration
- continuity, actuation, and visual inspection
- RoHS and REACH production documentation
Compare interface options
| Service | Best Fit | Construction | Review Risk |
|---|---|---|---|
| Custom membrane switch | Thin sealed panels | PET/PC overlay, silver circuit, tail, connector | Tail routing, adhesive surface, dome force |
| Membrane keypad | Repeated key operation | Embossed overlay, metal domes, spacer venting | Key pitch, legend wear, dome life |
| Graphic overlay | Front-panel labeling and windows | PET/PC film, hard coat, screen print, adhesive | Window clarity, color, cleaner exposure |
| Silicone keypad | Molded travel and soft feel | Silicone rubber, carbon pill, coating, PCB pads | Web thickness, compression set, light bleed |
| Capacitive touch panel | Smooth sealed HMI surface | Sensor, controller, front lens, tail | Water, gloves, EMC, grounding |
| HMI assembly | Drop-in control module | Overlay, switch, PCB/FPC, hardware, cable | Assembly stack, test plan, serviceability |
What to send for RFQ
