Key Advantages

1. One-Piece Molded Silicone Elastomer

Manufactured using Liquid Silicone Rubber (LSR) one-shot molding, all 16 keys are seamlessly connected to the base, ensuring a robust structure with no risk of loose components. The soft, resilient silicone delivers consistent tactile feel and excellent fatigue resistance, with a service life exceeding 1 million cycles.

2. Standard 4×4 Matrix Layout

16 keys arranged in a standard 4-row × 4-column matrix, with 8 external interface pins (4 rows + 4 columns) compatible with common microcontroller scanning schemes. Directly connect to Arduino, Raspberry Pi, and other development boards with simple code for key reading – lowering development barriers.

3. Reliable Conductive Solutions

Integrated conductive carbon pills or conductive rubber contacts at the button base – rows and columns are connected when pressed and disconnected upon release. Contact resistance as low as 50-100Ω (carbon pill solution) ensures stable, bounce-free signals and supports rapid key repeat detection.

4. Silent & Comfortable Operation

Silicone material provides a soft tactile feel with key travel of 0.3mm - 3.0mm (customizable). Silent operation makes it suitable for noise-sensitive environments such as libraries, laboratories, and hospitals. Matte surface is slip-resistant and wear-resistant, reducing fatigue during extended input sessions.

5. Fully Customizable

Key legends, colors, and layout arrangements can all be customized. Supports silk screening, laser engraving, and other marking processes to meet functional labeling requirements across different industries. Thickness, hardness, and actuation force parameters are also adjustable.
