About the Course:

This EV Pyrotechnic Safety Switch Inspection microcredential trains EV technicians to understand and inspect pyrotechnic safety switches used to protect high-voltage electrical systems during emergency or fault conditions. 

Learners will identify the major components of a pyrotechnic safety switch, understand its purpose within the EV high-voltage system, and perform visual inspections of the switch, electrical connections, wiring, and surrounding components. The course emphasizes safe inspection practices, high-voltage awareness, and identification of visible damage or abnormal conditions. 

Technicians will also learn to recognize potential inspection findings, follow appropriate safety procedures, and verify the condition of the pyrotechnic safety switch and its connections. 

Learning Objectives:

  • Identify the pyrotechnic safety switch and its major components 
  • Understand the purpose of the pyrotechnic safety switch in EV high-voltage systems 
  • Identify the switch location and its connection within the high-voltage circuit 
  • Inspect the switch, wiring, connectors, and surrounding components 
  • Recognize visible damage, loose connections, corrosion, or abnormal conditions 
  • Follow appropriate high-voltage safety procedures during inspection 
  • Identify and document inspection findings according to established procedures 
  • Verify the overall condition of the pyrotechnic safety switch 

This EV Pyrotechnic Safety Switch Inspection training is delivered through our LMS and is available as both web-based and immersive VR training.

At ImmerseLearn, we equip EV technicians with practical skills for safely inspecting high-voltage safety components. This microcredential strengthens component identification, inspection accuracy, high-voltage safety awareness, and fault recognition through immersive VR-based learning. 

Pyrotechnic Safety Switch Fundamentals −
Learn the purpose, function, and role of pyrotechnic safety switches within EV high-voltage systems. Technicians gain practical understanding of the switch, its connections, and its role in high-voltage circuit protection.
Safety Switch Component Inspection +
Practice identifying and visually inspecting the pyrotechnic safety switch, wiring, connectors, and related components. Learners focus on recognizing visible damage, loose connections, corrosion, and other abnormal conditions.
High-Voltage Inspection Safety +
Develop safe inspection practices for EV high-voltage systems. Learners will apply appropriate safety procedures and precautions while working around pyrotechnic and high-voltage components.
Inspection Findings and Verification +
Apply inspection skills to identify abnormal conditions and verify the overall condition of the pyrotechnic safety switch. Learners will practice recognizing and documenting relevant inspection findings according to established procedures.
What is an EV pyrotechnic safety switch? +
An EV pyrotechnic safety switch (also called a pyrotechnic fuse or pyrofuse) is a high-voltage protection device that can rapidly disconnect the battery circuit during a crash or critical fault to help protect people and vehicle systems.
How does a pyrotechnic fuse/safety switch work? +
When triggered by the vehicle safety system, the pyrotechnic element opens the high-voltage circuit very quickly. This training covers how to recognize the switch, its connectors, and why correct inspection matters before and after service.
How do you inspect an EV pyrotechnic safety switch? +
Inspection typically includes verifying vehicle power-down and high-voltage isolation, locating the switch, checking wiring and connectors for damage or corrosion, looking for signs of prior activation, and documenting findings per procedure.
What safety precautions are required for EV pyrotechnic safety switch inspection? +
Follow high-voltage PPE and lockout practices, confirm the system is de-energized before inspection, avoid probing live HV circuits, and use the approved workflow taught in this EV pyrotechnic safety switch inspection training for EV technicians.

By completing this microcredential, technicians will develop the knowledge and practical skills needed to safely identify, inspect, and verify pyrotechnic safety switches in electric vehicles.
