Machine Interface: Switches & Keypads
We provide and integrate switch and keypad solutions designed for durability, usability, and reliable operation within complex electronic systems.
OVERVIEW
Machine interface design plays a critical role in how systems are operated, maintained, and understood in real-world environments. Repeated use, environmental exposure, and variation in how systems are handled all place demands on interface reliability and performance.
We provide custom switch and keypad assemblies as part of complete user interface systems, supporting both standard and bespoke requirements. From material selection and sealing through to integration within the wider system, we help ensure interfaces are robust, responsive, and fit for their operating environment.
By aligning interface design with system requirements, we support improved usability, consistent performance, and reduced risk of operator error across demanding applications.

CAPABILITIES
What We Do
We combine engineering, supply chain management and quality control to deliver reliable switch and keypad assemblies – from single components to fully integrated interface modules.
Engineering & DFM
Our engineering team provides guidance from the earliest stages, advising on actuation forces, dome selection, travel, environmental sealing and visibility options. We support artwork development for printed or laser‑etched legends, and offer phosphorescent or backlit features for low‑light environments. Fast prototyping loops allow you to evaluate feel, clarity and usability in real operating conditions before moving to production.
Box Builds & Systems Integration
We build complete interface assemblies ready for installation – including carriers, gaskets, illumination layers, wiring looms, connectors and integrated PCBs. Every unit is produced to your bill of materials and tested for fit, function and durability. This integrated approach simplifies your supply chain, shortens build time and ensures each assembly arrives line‑ready.
UK & Global Manufacturing
Our UK and global manufacturing resources provide flexible production routes for switch and keypad programmes of varying complexity, volume and lead-time requirements. Consistent quality controls, documentation, testing and traceability help ensure reliable production performance while supporting continuity, scalability and long-term supply chain resilience.
Supplier & Project Management
We coordinate materials, tooling, coatings, graphics, lighting components and any sub‑assemblies. You receive one consolidated schedule, one documentation flow and one quality process. We manage risk throughout the lifecycle – including obsolescence checks and material changes – ensuring long‑term stability for your switch or keypad programme.
Quality & Compliance
Our quality and compliance processes support traceability, consistency and reliable performance throughout the switch and keypad product lifecycle. Through controlled documentation, inspection, testing and verification, we help reduce risk, maintain confidence in every build and ensure assemblies meet technical, regulatory and customer requirements.
PRODUCT DETAILS
Choose from proven standard components or fully customised assemblies. We tailor sealing, materials, lighting, legends and actuation feel to your product’s operating conditions and user requirements.
Switches (standard or customised)
We supply toggle, rocker, push, rotary and slide switches – available as off‑the‑shelf parts or customised for your required actuation force, contact rating, IP level and marking style. Each switch is specified to suit its electrical load, environment and expected duty cycle to ensure stable long‑term performance.
Advanced Plastic Keypads
Durable injection‑moulded plastic or rubber keypads offering excellent clarity, impact resistance and design flexibility. High‑contrast legends and optional backlighting improve visibility, while tactile or non‑tactile actuation can be tailored to operator preference. Ideal for industrial, medical and rugged handheld devices requiring long‑lasting markings.
Silicone Rubber Keypads
Custom‑manufactured silicone keypads built to your drawings. Silicone offers natural sealing, chemical resistance and strong tactile feel – making it suitable for medical devices, industrial machinery, communications hardware and applications exposed to moisture or regular cleaning.
Phosphorescent Keys
Keys that absorb ambient light and emit a soft glow to ensure visibility in low‑light or no‑power conditions. Ideal for emergency response, safety systems or environments where powered lighting cannot be guaranteed.
Laser‑Etched Legends
Laser‑etched legends provide permanent, wear‑resistant markings that don’t fade, peel or degrade – even after years of cleaning or heavy use. A strong choice for medical and industrial interfaces requiring long‑term clarity.
Epoxy‑Coated Keypads
A hardened epoxy layer improves scratch resistance and gives keys a firmer feel. This finish is ideal where frequent use, abrasion or chemical exposure may impact keypad longevity.
3D Protruding Keypads
Raised three‑dimensional key profiles provide clear tactile separation, helping operators identify inputs by touch alone – ideal for gloved environments, low‑visibility settings or safety‑critical applications.
Concave Printed Keypads
Concave surfaces guide the user’s finger to the centre of each key, reducing accidental presses. Printed legends remain clear and consistent, supporting precision control applications.
Mix‑and‑Match Keypad Finishes
Combine coatings, colours, textures and key shapes within a single keypad. Highlight critical keys, separate functional areas or enhance usability without increasing assembly complexity.
Membrane Switches
Thin, sealed membrane switches with tactile or non‑tactile feel. Custom overlays can be designed for colour, branding and texture, with optional integrated LEDs. A durable, low‑profile solution for compact devices requiring easy cleaning and simple operation.
Helpful guidance for materials, sealing and visibility
Access reference materials covering keypad construction, lighting options, sealing techniques and cleaning compatibility to support faster decision‑making during development.

FAQS
Commonly Asked Questions
These FAQs reflect the questions we hear most often. Our engineering team can also review drawings or advise on specific applications.
How do I choose between silicone rubber and plastic keypads?
Silicone offers strong sealing, chemical resistance and defined tactile feel — ideal for harsh environments. Plastic keypads provide higher impact resistance and support moulded shapes or integrated light guides. We can prototype both options and help compare tactile response, readability and durability based on your specific use case.
What are the best options for low‑light visibility?
Choose LED backlighting for controlled, powered illumination, or phosphorescent keys for passive glow‑in‑the‑dark visibility. We help determine which approach suits your lighting environment, power availability and operator needs.
Can you supply full keypad or switch assemblies?
Yes – we supply complete assemblies including carriers, PCBs, lighting layers, gaskets, wiring looms and connectors. Each unit is tested for fit, functionality and durability and delivered line‑ready.
How quickly can samples or early production be supplied?
We provide 24–48‑hour dispatch on many UK‑stocked components. Custom assemblies follow tooling and verification steps, and we offer accelerated development paths when timelines are tight.
Are laser‑etched legends more durable than printed ones?
Yes. Laser‑etched legends resist fading, abrasion and chemical cleaning far better than printed alternatives. They are ideal for equipment that undergoes frequent handling or requires long‑term clarity.
What certification and documentation can you provide?
We offer traceable documentation including RoHS/REACH, material certifications, biocompatibility information when needed, and FAI/PPAP packs. All production follows ISO 9001 and ISO 13485 frameworks for quality and traceability.
Can a single keypad include different textures or finishes?
Absolutely. Multiple coatings, colours, textures and key shapes can be combined within a single keypad to enhance usability, highlight critical functions or refine product styling – without increasing assembly complexity.
