# LSR Key Cap for Smart Lighting
Product of 橡楚（湖北）橡胶有限公司

LSR (Liquid Silicone Rubber) key caps for smart lighting are custom-molded silicone components designed to provide tactile, durable actuation for touch control and physical button interfaces on smart home lighting fixtures, smart panel switches, and connected commercial lighting systems. As a specialized LSR product manufacturer based at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, 橡楚（湖北）橡胶有限公司 formulates these key caps to meet the unique performance requirements of smart lighting devices, balancing soft tactile feedback, long-term mechanical stability, and compatibility with modern industrial assembly processes.
Unlike general-purpose rubber or plastic key caps, our LSR smart lighting key caps are engineered to address common pain points in connected lighting devices: inconsistent actuation force after repeated use, discoloration from long-term UV or LED exposure, poor tactile feel that undermines user experience, and compatibility issues with high-volume automated insertion assembly. Each key cap is manufactured from 100% food-grade medical-grade raw LSR material (when specified) with consistent molding accuracy, ensuring uniform performance across every production batch. Our core production capability focuses exclusively on custom liquid silicone rubber components, allowing us to adapt key cap designs to fit any smart lighting form factor, from compact round buttons for table lamps to multi-key arrays for wall-mounted smart switch panels.

Our LSR key caps are manufactured from high-purity addition-cure liquid silicone rubber, with the following core material properties:
We control physical parameters to meet the daily actuation requirements of smart lighting buttons:
Our LSR key caps are compatible with standard smart lighting assembly processes, with the following design and processing parameters:
---
Unlike thermoplastic key caps that harden or crack over time, and low-cost silicone that suffers from permanent compression set after thousands of actuations, our addition-cure LSR maintains consistent hardness and compression recovery over more than 1 million actuation cycles. This ensures the key cap retains the same soft, responsive tactile feel throughout the service life of the smart lighting fixture, eliminating the "mushy" unresponsive button feel that plagues lower quality components.
Most modern smart lighting controls include LED indicator backlighting to show device status in low-light environments. Our translucent LSR key cap formulations provide uniform light diffusion, eliminating hot spots from individual LED chips and producing a soft, even glow that is easy on the eyes. We also offer custom tinted formulations to match any branding or design requirement, with proven resistance to yellowing from long-term LED exposure, maintaining consistent optical performance for years.
All our LSR key cap formulations are RoHS and REACH compliant, with low VOC emissions and no toxic heavy metals or phthalates, making them safe for indoor residential and commercial use. When food-grade or medical-grade material is requested, our key caps meet FDA 21 CFR 177.2600 requirements, suitable for smart lighting fixtures in kitchens, bathrooms, and healthcare facilities where contact with skin is common.
As a dedicated LSR manufacturer, we support custom tooling and molding for any key cap shape, size, and texture, from small 5mm round buttons for portable smart lamps to large 100mm multi-key arrays for whole-home smart switch panels. We can also integrate design features such as integrated anti-dust gaskets, snap-fit mounting tabs, and textured surfaces for improved grip, eliminating the need for secondary assembly steps and reducing total production cost for smart lighting OEMs.

At 橡楚（湖北）橡胶有限公司, we implement strict quality control processes aligned with our ISO 9001 certification to ensure every LSR key cap meets the specified performance requirements. Our quality assurance process includes incoming material inspection for raw LSR to verify purity and hardness, in-process dimensional checks for every production run, and final functional testing for compression set, color consistency, and surface defects before shipment.
We maintain full traceability for every production batch, allowing us to quickly address any quality concerns and maintain consistent performance across repeat orders. All our products are tested to meet international environmental standards including RoHS and REACH, in addition to the specific performance requirements outlined in the technical specifications above.
