Introduction

The Cummins 4328672 Pressure Switch is a component designed for use in commercial trucks. It serves to monitor and regulate pressure within specific systems, ensuring that operations remain within safe and efficient parameters. This switch is integral to maintaining the performance and reliability of truck systems by providing accurate pressure readings and facilitating timely responses to pressure changes ¹.

Basic Concepts of Pressure Switches

A pressure switch is a device that opens or closes an electrical circuit in response to a specific pressure threshold. It operates by using a diaphragm or piston that moves in response to changes in pressure. When the pressure reaches a predetermined level, the diaphragm or piston activates a mechanism that either opens or closes the electrical circuit, thereby controlling the operation of connected systems. Pressure switches are commonly used in various applications, including HVAC systems, hydraulic systems, and automotive applications, to ensure that systems operate within desired pressure ranges ².
