At HEP’s Precision Engineering Electrical division in Delano, every component is built to outperform expectations. Our electrical switches are crafted to micron-level tolerances, endurance-tested in rigorous lab conditions, and stocked locally so you can keep production moving without delay. From high-cycle automation cells to mission-critical control panels, you’ll feel the difference the moment each switch clicks into place.
Choose from a full spectrum of tactile, toggle, push-button, and rotary designs, then collaborate with our engineers to customize ratings, materials, and terminations that fit seamlessly into your build. With rapid prototyping, same-day shipping across Delano, and a support team that speaks your language, HEP delivers the reliability, precision, and service that turn good projects into great ones.
FAQs
What types of electrical switches do you manufacture in your Delano facility?
Our Delano plant is equipped to engineer and manufacture a wide range of switches, including toggle, rocker, push-button, micro, rotary, DIP, and custom momentary or latching devices. We handle both low-voltage signal switches for electronics and high-current power switches up to 600 V AC/300 A, giving local customers a one-stop source for virtually any precision switch requirement.
How does precision engineering improve switch performance and reliability?
Precision engineering means we machine contact carriers, actuator mechanisms, and housings to micron-level tolerances. Tighter tolerances ensure uniform contact pressure, minimal arcing, and consistent actuation force, which translate into lower contact resistance, longer electrical life cycles, and smoother user feel. We also perform statistical process control (SPC) on every batch to catch minute dimensional drifts before they affect field performance.
Can you customize electrical switches for specific applications or industries?
Yes. About 60 % of our production in Delano is either fully custom or semi-custom. We can modify actuation force, travel, termination style (PCB pins, screw, quick-connect, solder), sealing level (IP54–IP67), illumination options, and housing materials to meet UL 94, FDA, or MIL-SPEC requirements. Our engineers collaborate with you at the concept stage, create 3-D models in SolidWorks, build rapid prototypes on-site, and conduct validation testing to ensure the switch integrates seamlessly into your product.
What quality standards and certifications do your switches comply with?
The facility is ISO 9001:2015 and IATF 16949 certified. All production switches are 100 % electrically tested, and models can be supplied with UL, CSA, and CE markings. For aerospace or defense contracts we follow AS9100 documentation practices and can provide first-article inspection reports (FAIR). RoHS, REACH, and California Prop 65 compliance are standard, with full material traceability back to the mill certificates.
What is the typical lead-time for prototype and production runs?
Rapid prototypes can be turned around in as little as 5–7 business days thanks to our in-house CNC machining and 3-D printing cells. Standard production quantities up to 10 k units usually ship within 4–6 weeks after design approval. For larger volumes or highly specialized tests (salt fog, thermal shock, HALT), lead-times may extend to 8–10 weeks. We offer expedited options and kanban stocking agreements for recurring orders to keep your assembly lines running without interruption.
Do you provide engineering support and after-sales service to clients in and around Delano?
Absolutely. Local customers benefit from on-site application engineering, line-side troubleshooting, and training sessions at no additional charge. Our field technicians can visit your facility within 24 hours, and remote support is available 24 / 7. Every switch ships with a two-year workmanship warranty, and we maintain a dedicated repair/calibration lab in Delano to refurbish or re-rate switches, extending their service life and lowering total ownership cost.
