P+R Composite Keys for Gaming, Industrial & Automotive Controls

Product Overview

The P+R Composite Key is a precision-engineered button that integrates a rigid plastic base with a soft silicone contact layer, delivering the optimal balance of structural stability and tactile comfort for POS terminals and other demanding interface applications. Unlike conventional all-plastic buttons, the P+R construction combines the precise dimensional control of injection-molded plastic with the responsive, cushioned feel of silicone, significantly reducing operator fatigue during repeated use—a critical factor for POS terminals in retail, hospitality, and banking environments where staff operate keypads continuously throughout the day.

The three-layer architecture—a rigid support frame, an elastomeric contact layer, and a conductive switching element—ensures consistent actuation force and reliable electrical contact across millions of cycles. Leveraging over 20 years of manufacturing expertise, ES Silicone has refined the dual-material molding process to achieve tolerances as tight as ±0.02mm. Our in-house silicone and plastic factories, combined with our senior engineering team and 1,000+ completed P+R projects, make this design the preferred interface solution for POS terminals, gaming controllers, industrial handhelds, and automotive electronics where durability and user experience are paramount.

Core Advantages

1. Laser-Engraved Backlight Compatibility for Enhanced Visibility : Precision laser engraving creates translucent legends with light transmission exceeding 85%, enabling integrated LED backlighting and breathing light effects. ES Silicone's advanced laser systems, backed by 20+ years of process refinement, ensure consistent engraving depth and uniform illumination across every key—critical for POS terminals used in low-light retail and hospitality environments.

2. Exceptional Durability with Over 1 Million Cycle Life : The P+R construction withstands rigorous endurance testing exceeding 1 million actuations under GB/T 2423 standards. With our own silicone and plastic factories, we implement strict quality control protocols throughout manufacturing, including automated optical inspection and force-displacement testing, to verify that each key maintains its elasticity, rebound characteristics, and structural integrity over its entire service life. Our 1,000+ completed P+R projects give us deep experience in meeting the durability demands of POS terminal applications.

3. Precision Dual-Material Molding for Superior Dimensional Accuracy – Utilizing advanced two-shot injection molding technology, the plastic base and silicone contact layer are bonded seamlessly in a single process, eliminating the need for secondary assembly. ES Silicone's in-house engineering team conducts comprehensive DFM reviews to optimize mold design and process parameters, achieving dimensional tolerances as tight as ±0.02mm. With our own mold-making capabilities and over 20 years of experience, we ensure consistent fit across high-volume production runs for POS terminals and other demanding applications.
