Product Overview
The Wear-resistant Liquid Silicone (LSR) Remote Control Keypad Custom is a high-performance input component engineered for long-lasting, reliable operation across consumer electronics, industrial control, medical equipment, and automotive infotainment systems. Manufactured via precision injection molding of food-grade or industrial-grade liquid silicone rubber, this custom keypad combines exceptional wear resistance, responsive tactile feedback, and excellent environmental stability to outperform traditional thermoplastic or solid silicone keypad alternatives.
Our custom LSR remote control keypads support full design customization: key layout, actuation force, surface finish, backlighting compatibility, and conductive layer configuration can be tailored to match your product’s exact functional and aesthetic requirements. Core selling points include a 10-million+ actuation lifecycle, resistance to UV degradation, water and dust ingress, and compatibility with low-cost, high-volume mass production, making it the ideal input solution for remote controls intended for frequent use in harsh or high-traffic environments.

Product Advantages
1. Industry-Leading Wear Resistance for Extended Lifecycle
Our LSR keypads feature a proprietary wear-resistant surface formulation and optional UV-cured protective overcoating, delivering 2–5x longer surface printing lifespan than standard silicone keypads. The keypad structure is engineered to withstand over 10 million actuation cycles without loss of tactile feedback or contact failure, making it suitable for high-traffic applications such as hotel TV remotes, industrial equipment controllers, and public kiosk input devices. The carbon or metal contact layer is bonded directly to the LSR substrate during molding, eliminating delamination risks common with post-assembly contact attachments.
2. Superior Environmental Stability
Unlike thermoplastic keypads that crack, fade, or become brittle under extreme temperatures or UV exposure, our LSR remote control keypads maintain consistent performance across a -40°C to +120°C operating range. The material is inherently resistant to UV radiation, moisture, oils, and common household chemicals (including disinfectants, detergents, and food spills), making it suitable for outdoor, automotive, medical, and food service applications. Fully sealed custom configurations meet IP68 ingress protection requirements, allowing the keypad to be submerged in up to 1.5 meters of water for 30 minutes without functional damage.
3. Customizable Tactile and Aesthetic Performance
We support full customization of actuation force, key travel, and tactile response to match user experience requirements: soft 80g actuation force for elderly-focused consumer remotes, firm 350g actuation for industrial control remotes to prevent accidental inputs, and adjustable tactile bump ratios (15–40%) for ideal feedback. Surface finish options include matte, textured, or glossy, with support for laser etching, pad printing, or in-mold labeling for permanent, wear-resistant key legends. Translucent LSR grades are available for uniform RGB backlighting, with light diffusion additives to eliminate hotspots and ensure consistent illumination across all keys.
4. Cost-Effective High-Volume Manufacturing
LSR injection molding enables high-volume production with minimal secondary processing, reducing per-unit costs by 15–30% compared to assembled solid silicone keypads. The automated molding process delivers consistent part quality with <0.1% defect rates for mass production runs, and supports overmolding onto plastic remote control housings or PCB substrates to reduce assembly time and labor costs. The low curing temperature of LSR also allows integration with heat-sensitive electronic components during the molding process, eliminating additional assembly steps.
Applications
- Consumer Electronics: Smart TV remotes, set-top box controllers, home automation remotes, gaming console peripherals, and air conditioner remote controls, where long lifespan and resistance to household spills are required.
- Industrial Control: Industrial machinery remote controls, construction equipment remote interfaces, factory automation HMI keypads, and agricultural equipment controllers, which demand resistance to vibration, extreme temperatures, and oil/dust exposure.
- Medical Equipment: Patient monitor remote controls, portable diagnostic device keypads, and medical bed controllers, which require biocompatible (ISO 10993 certified) materials that can withstand repeated disinfection with alcohol and hospital-grade disinfectants.
- Automotive: In-car infotainment remote controls, steering wheel control keypads, and rear-seat entertainment remotes, which require UV resistance, wide temperature tolerance, and compliance with automotive flame-retardant (UL 94 V-0) and low VOC emission standards.
- Public and Commercial Use: Hotel TV remotes, restaurant ordering device keypads, self-service kiosk input interfaces, and public broadcasting system controllers, which demand high wear resistance and waterproofing for frequent use by untrained users.

Quality Assurance
Our LSR remote control keypads are manufactured in an ISO 9001:2015 certified facility, with a multi-stage quality control process to ensure consistent performance:
- Incoming material inspection: All LSR raw materials undergo batch testing for hardness, tensile strength, and compliance with regulatory standards before entering production.
- In-process inspection: 100% dimensional inspection of the first 10 parts per production run, followed by random sampling every 30 minutes to verify actuation force, contact resistance, and dimensional tolerance.
- Finished product testing: Every batch undergoes lifecycle testing (10 million actuation cycles), wear resistance testing, temperature cycling testing (-40°C to 120°C for 100 cycles), and waterproofing verification for sealed configurations.
- Certification support: All products can be supplied with full test reports and compliance documentation, including FDA, RoHS, REACH, UL 94, and ISO 10993 certificates as required for your target market.
We offer a 12-month warranty against manufacturing defects, including cracking, printing peeling, contact failure, and loss of tactile feedback under normal use conditions. Our engineering team also provides post-sales support for design optimization, material selection, and assembly process guidance to ensure seamless integration into your final product.
