Engineered With Precision | Electrical Switches | Electrical | Norris
Experience the assurance that comes from HEP’s relentless focus on precision. In our Norris facility, expert craftsmen and engineers collaborate to develop electrical switches that stand up to the most demanding industrial and commercial applications. Each mechanism is machined, assembled, and tested to microscopic tolerances, ensuring smooth actuation, reliable signal integrity, and long-term durability even in harsh environments.
Whether you’re designing a mission-critical control panel or upgrading legacy infrastructure, you’ll find our solutions remarkably easy to specify, install, and maintain. From tactile feedback tuned for operator comfort to contact materials that resist arc erosion, every detail is optimized for performance and safety. Discover how HEP turns exacting standards into everyday reliability—then put that reliability to work in your next project.
FAQs
What makes Norris engineered-with-precision electrical switches different from standard switches?
Norris switches are manufactured with tighter tolerances, premium contact materials, and advanced actuator mechanisms. This results in lower contact resistance, longer mechanical life cycles (up to 1 million operations), and superior feel compared with commodity switches. Our precision engineering also guarantees consistent performance across extreme temperatures and demanding industrial environments.
Which certifications and compliance standards do Norris electrical switches meet?
All Norris precision switches are UL and cUL listed, CE marked, and RoHS compliant. Selected series also carry IEC 61058 and ENEC approvals for international use. Every production batch undergoes 100 % functional testing and statistical sampling for dielectric strength, insulation resistance, and endurance according to IEC 60669 guidelines.
Can I customize a Norris switch for my specific application?
Yes. We provide a full range of customization options, including actuator styles (rocker, push-button, toggle, slide), contact configurations (SPST, SPDT, DPDT, etc.), illumination colors, panel mounting options, and termination types. Our engineering team can even tailor actuation force, travel, and sealing (up to IP67) to fit specialized requirements. Typical prototypes are delivered within 3–4 weeks after specification sign-off.
How should Norris precision switches be installed to ensure optimal performance and safety?
Always disconnect power before installation. Verify that the switch’s rated voltage and current exceed the load requirements. Mount the switch on a clean, flat panel surface to avoid mechanical stress, and use the recommended torque for panel nuts or screws (usually 0.6–1.0 N·m). For solder terminals, maintain a soldering temperature below 350 °C and complete each joint within 3 seconds to prevent heat damage. After wiring, perform a continuity test to confirm correct connections.
What maintenance is required to prolong the life of a Norris switch?
Our switches are designed for maintenance-free operation under normal conditions. However, in harsh or dusty environments, periodic inspection is advised: 1) Isolate power, 2) Clean external surfaces with a dry lint-free cloth and compressed air, 3) Check terminals for looseness or corrosion, tightening as necessary, and 4) Verify actuation feel—any excessive stiffness or looseness may indicate contamination or wear. Replace the switch if abnormalities are found.
Does Norris offer technical support and documentation for its precision switch lines?
Absolutely. Each product page provides downloadable datasheets, 3D CAD models, wiring diagrams, and compliance certificates. Our application engineers are available via phone, email, or live chat to help with selection, circuit integration, and regulatory questions. We also offer on-site seminars and webinars covering best practices for switch specification, installation, and troubleshooting.
