P+R Key

The P+R key (Plastic + Rubber) is a composite key structure commonly used in electronic devices, combining plastic and rubber materials to enhance the key’s tactile feel, sealing, and durability. Typically, the plastic component provides structural support and aesthetic design, while the rubber component offers a soft touch and improved press feedback. This combination effectively enhances the key’s water and dust resistance, making it suitable for a wide range of applications, especially in automotive, home appliance, and industrial equipment.

The production process for P+R keys generally involves two-shot injection molding, where the plastic and rubber parts are separately molded and then combined. This process endows the key with the rigidity of plastic and the flexibility of rubber, ultimately improving the product’s usability and durability.
