At HEP’s Whitwell facility, precision engineering meets practical innovation to deliver robust, UK-manufactured electrical switches that you can trust in the most demanding environments. From the first CAD sketch to final quality assurance, every component is produced in-house, ensuring micron-level tolerances, flawless contact integrity and zero-compromise safety. Whether you’re designing a new automation line, upgrading control panels or specifying safety interlocks for critical medical equipment, our experienced engineers collaborate with you to tailor each switch to exact voltage, load and environmental requirements.
Beyond performance, we understand the urgency of downtime and tight production schedules. That’s why we stock a comprehensive range of electrical switches ready for next-day dispatch across Derbyshire and the wider UK, backed by rapid prototyping and low-volume custom runs when standard options won’t do. Speak with our Whitwell team today and discover how precision engineering can keep your systems clicking with confidence.
FAQs
What types of electrical switches do you manufacture at your Whitwell facility?
We specialise in a wide range of precision-engineered electrical switches, including toggle, rocker, push-button, rotary, micro, and limit switches. Our Whitwell plant also manufactures sealed and IP-rated variants for harsh environments, as well as low-profile and high-current models for specialised industrial applications.
Can you design and produce custom electrical switches to suit unique project requirements?
Yes. Our in-house engineering team in Whitwell offers a full custom design service—from initial concept sketches and 3D CAD modelling to rapid prototyping, pre-production sampling, and final manufacture. Whether you need non-standard actuation forces, bespoke form factors, or unique contact materials, we can tailor a switch solution precisely to your specifications.
Which quality standards and certifications do your switches meet?
All switches are manufactured under our ISO 9001:2015 certified quality management system. Where required, products are designed to meet or exceed IEC, BS EN, UL, and CE standards, and we can supply RoHS and REACH compliance documentation on request. For specialised sectors, we also offer ATEX-approved and MIL-spec options.
How do you ensure precision and reliability during switch production?
We use CNC machining, automated pick-and-place assembly, and 100 % electrical and mechanical testing at every production stage. Critical tolerances are verified with CMM (Coordinate Measuring Machine) inspection, while contact resistance, dielectric strength, and actuation life are validated using dedicated test rigs. Statistical process control (SPC) data is logged in real time to maintain consistent quality.
What are your typical lead times for orders placed from Whitwell and surrounding areas?
For catalogue switches, our standard turnaround is 3–5 working days for quantities up to 1,000 units. Custom or high-volume orders usually ship within 3–4 weeks, depending on material availability and tooling requirements. We also run an expedited service for urgent projects that can deliver in as little as 48 hours—please contact our sales team for current capacity.
Do you provide installation guidance and after-sales support?
Absolutely. Each shipment includes detailed installation datasheets and wiring diagrams. Our technical support line is staffed by qualified engineers who can assist with integration, troubleshooting, and regulatory documentation. We provide a 24-month warranty on all switches, and local Whitwell service engineers can arrange on-site visits if required.
