My 2025 Summer

Engineering Internship

Hydra-Electric Company

In 1961, Hydra-Electric developed switches for NASA’s Mercury project, which sent John Glenn into orbit. The company also contributed to the 1969 Apollo 11 mission and continues to innovate in aerospace switch and sensor technology today.

Throughout the summer following my second year, I spent my internship intensively learning how to properly 3D model, assemble, and analyze the machining quality of aircraft switches. I also reverse engineered fixtures and revised outdated drawings from AutoCAD to Solidworks. I shadowed various colleagues in the machine shop and assembly department to sharpen my skills in manufacturing processes, including disk spring manufacturing and pressure testing the quality of specific switch models. Thanks to the help of my wonderful team, I earned my CWSA Certification after completing my internship!

Project Outline:

  • Replenish outdated switch AutoCAD drawings onto Solidworks and integrate into company Product Data Management

    • Revise redlines on drawings and ensure dimensions are fully correct

  • Assembly and Disk Spring Manufacturing

    • Understand traveler and full manufacturing processes

    • Form and temper disk springs used to activate electrical signals on switches

    • Clean, carefully assemble, and cryo/shock test new models of switches to simulate real flight conditions

  • Machine Shop

    • CNC Machining

    • Precise tolerancing and measuring

  • FEA Simulation

    • Stress testing diaphragms
