Cummins®

The Cummins 3050692 Magnetic Switch is a critical component for commercial trucks, integral to the vehicle’s electrical system. Understanding its function and role is essential for maintaining and troubleshooting truck electrical systems.

Basic Concepts of Magnetic Switches

A magnetic switch, or magnetic reed switch, operates using a magnetic field. It consists of ferromagnetic contacts in a glass tube, positioned between two poles of a permanent magnet. An external magnetic field causes the contacts to close, allowing current flow. This mechanism is utilized in automotive systems for security, fuel level indicators, and engine management ¹.
