From compact toggle designs to fully sealed rotary mechanisms, HEP’s precision-engineered electrical switches are crafted in Winfield to give technicians and OEMs rock-solid performance in the most demanding environments. Each unit is machined to micron-level tolerances, assembled under strict quality controls, and 100 % tested before it reaches your panel—so every flip, push, or twist feels as crisp on the thousandth cycle as it did on the first.
Choose from a wide portfolio of configurations, amperage ratings, and mounting options, or work with our engineers to create a custom solution that slots seamlessly into your build. Whether you’re upgrading industrial automation, outfitting marine controls, or refining a prototype, HEP delivers switches that cut downtime, simplify installation, and meet the latest UL and IEC standards.

FAQs
What types of precision-engineered electrical switches do you manufacture in your Winfield facility?
We design and build a full range of low-, medium-, and high-voltage switches, including toggle, rocker, rotary, micro-limit, and snap-action models. Each unit is engineered to tight tolerances (±0.01 mm typical) to ensure repeatable actuation forces and long-term reliability for industrial automation, medical devices, aerospace, and custom OEM applications.
Can you customise switch specifications for unique projects?
Yes. Our engineering team can tailor actuation force, travel distance, contact plating, ingress-protection (up to IP68), housing materials, terminal styles, and even tactile feedback profiles. We follow a structured NPI (New Product Introduction) workflow—requirements capture, 3-D modelling, rapid prototypes, environmental and life-cycle testing—before moving to full production in Winfield.
How do you guarantee quality and compliance?
All production runs are controlled under our ISO 9001:2015 and AS9100-certified QMS. We perform 100 % functional testing, automated optical inspection, and statistical process control on critical dimensions. Switches can be supplied with UL, CSA, or CE markings and RoHS/REACH declarations. Full material traceability and first-article inspection reports are available on request.
What is the typical lead time for precision switches?
For catalogue parts, standard lead time is 2–3 weeks ex-works Winfield. Custom or modified designs average 4–6 weeks, depending on tooling requirements and component availability. We keep safety stock on high-volume items to support expedited (48- to 72-hour) shipments when needed.
How long will your switches last in service?
Life expectancy depends on load and environment, but our precision micro-switches are rated for up to 10 million mechanical cycles at 25 °C and 1 million electrical cycles at rated load. All ratings are verified through accelerated endurance rigs that replicate real-world temperature, humidity, and vibration conditions.
Do you offer technical support and after-sales services in Winfield?
Absolutely. Our Winfield applications team provides on-site or virtual assistance with product selection, circuit integration, and failure analysis. We also offer custom harnessing, kitting, and Kanban replenishment programs to streamline your production line. If any issue arises, local engineers can inspect parts within 24 hours and coordinate immediate replacements or corrective actions.
