Introduction

The Cummins 2879794 Magnetic Switch is a component designed for use in commercial trucks. It serves a specific function within the vehicle’s electrical system, contributing to the overall operation and efficiency of the truck. Understanding its purpose and role is fundamental for maintaining and optimizing the performance of commercial vehicles.

Basic Concepts of Magnetic Switches

A magnetic switch, also known as a reed switch, operates using the principles of magnetism. It consists of two or more flexible metal contacts sealed within a glass tube. When a magnetic field is applied, these contacts either attract each other, closing the circuit, or repel each other, opening the circuit ¹. Magnetic switches are commonly used in automotive systems for various applications, including controlling electrical circuits, sensing positions, and activating or deactivating components based on magnetic fields.

Components of Cummins Kit 2879794: Magnetic Switch

The Cummins kit 2879794, which is a Magnetic Switch, comprises several essential components, each playing a critical role in ensuring the functionality and reliability of the switch. Below is a detailed description of each component and its role within the kit:

Magnetic Switches (2865519)

The kit includes two magnetic switches, which are the core components of the assembly. These switches are responsible for detecting the presence of a magnetic field, which triggers the switch to activate or deactivate electrical circuits. Their role is pivotal in ensuring the magnetic switch operates correctly in response to magnetic stimuli.

Vibration Isolators (3408250)

There are two vibration isolators included in the kit. These components are designed to minimize the transmission of vibrations from the engine or other machinery to the magnetic switch. By reducing vibrations, the isolators help maintain the precision and reliability of the switch’s operation, ensuring it functions smoothly even in environments with significant mechanical vibrations.

Heavy Hexagon Nuts (S224)

The kit contains two heavy hexagon nuts. These nuts are used to secure various components within the magnetic switch assembly. Their robust design ensures a tight and durable connection, which is essential for withstanding the mechanical stresses and vibrations that the switch may encounter during operation.

Lock Washers (S600)

Two lock washers are provided in the kit. Lock washers are critical for preventing the loosening of fasteners due to vibration or thermal expansion. By distributing the load and providing additional friction, these washers help maintain the integrity of the connections within the magnetic switch, ensuring that all components remain securely in place.

Plain Washers (S631)

The kit also includes two plain washers. These washers serve to distribute the load of the fasteners more evenly across the surfaces they connect. This helps prevent damage to the components and ensures that the magnetic switch operates within its designed parameters without undue stress on any single point.

Each of these components plays a vital role in the overall performance and durability of the Cummins kit 2879794 Magnetic Switch. The careful selection and integration of these parts ensure that the switch can operate reliably in a variety of demanding applications.

Conclusion

The Cummins 2879794 Magnetic Switch is a vital component in the electrical system of commercial trucks, designed to ensure efficient and reliable operation. Its robust construction, precise operation, and resistance to environmental factors make it a dependable choice for truck manufacturers and operators. Proper installation, maintenance, and adherence to safety practices are essential for maximizing the performance and longevity of this Cummins part.
