- **Caution**: 

### Q: What is the primary function of a disconnector in machinery?
**A**: A disconnector physically interrupts electrical or mechanical connections in trigger assemblies to ensure operational safety by isolating power or motion during maintenance or emergencies.

### Q: Why are materials like copper alloy and stainless steel used in disconnectors?
**A**: Copper alloy provides excellent electrical conductivity and corrosion resistance for contacts, while stainless steel offers durability and strength for mechanical components in harsh industrial environments.

### Q: What are the key components in a disconnector's bill of materials?
**A**: The main BOM components are the Contact Assembly (for electrical interruption), Insulation Housing (for safety isolation), and Operating Mechanism (for manual or automated control).
