Numeric Keypad
Industrial 4x3 Keypad KY2068A With Metal Dome Switches
KY2068A is a standard 12 key keypad in a 4-row by 3-column layout for access control locks, elevator panels and payment terminals.
Product Overview
KY2068A is a standard 12 key keypad in a 4-row by 3-column layout for access control locks, elevator panels and payment terminals. The SUS304 panel and precise metal dome switches give a crisp press that stays consistent through high-frequency public use. The PCB uses industrial immersion gold plating to hold conductivity under heavy workloads.
- Standard 4-row × 3-column layout drops into existing door and cabinet cutouts
- Industrial immersion gold plating on the PCB prevents oxidation of the contacts
- Precise metal dome switch gives crisp tactile response that does not soften with use
- SUS304 steel panel resists corrosion, scratching and attempted vandalism
- Sealed casing resists water ingress and dust for indoor or outdoor mounting
- Bespoke key labeling and multi-language characters for export builds
Application Scenarios
- Access control locks on doors and gates
- Elevator control panels
- Industrial automation equipment
- Payment terminals
- Cabinet password locks and public self-service devices
Who It Is For
- Door and cabinet lock manufacturers
- Elevator control panel builders
- Payment terminal OEMs
- Automation equipment integrators
Problems It Solves
- Contact oxidation causes intermittent keys, addressed by industrial immersion gold plating
- Membrane pads lose feel after heavy use, while the metal dome switch keeps its tactile response
- Export projects need local characters, met by multi-language key labeling
- Public keypads attract abuse, so the panel is SUS304 with impact resistance

How It Compares
| Membrane 4×3 keypads | Metal dome switches keep a crisp tactile response through high-frequency usage where membranes go dull |
|---|---|
| Standard tin plated PCBs | Industrial immersion gold plating enhances conductivity and prevents oxidation under heavy workloads |
| Plastic keypad housings | SUS304 steel gives anti-corrosion, anti-scratch and impact resistance against attempted vandalism |
