Critical Emergency Door Switch & Lock Assembly for School Buses | P/N: 66NX1-03030-A

Product Description

When Seconds Count, Trust in Unfailing Reliability.

For any school bus, the safety of its young passengers is the absolute highest priority. There is no room for compromise. Nanjing Dingguan Accessories Co., Ltd. manufactures this essential Emergency Door Switch and Lock Assembly, a critical component designed to ensure both security during transit and immediate access in an emergency.

This dual-function unit is engineered for one purpose: to perform flawlessly when it matters most.

In a critical situation, it provides a simple, fast, and reliable release mechanism, allowing for immediate evacuation.

Key Features:

  • Dual-Function Safety: Combines a secure, positive-locking mechanism for daily transit with an easy-to-operate emergency release handle.
  • Designed for Emergencies: Features a highly visible, intuitive handle designed for quick activation in high-stress situations.
  • Direct OEM Replacement: Engineered as a perfect substitute for part number 66NX1-03030-A, guaranteeing a seamless, direct-fit installation on compliant school bus models.
  • Durable Construction: Built from heavy-duty, corrosion-resistant materials to withstand daily use, vibration, and meet the rigorous safety standards required for school transport.
