Top 5 Pressure Switch Brands: What You Need to Know About Each

Pressure switches are integral to HVAC systems, ensuring they operate safely and efficiently. These components monitor air or gas pressure, ensuring the system performs as expected while protecting against dangerous conditions such as overheating or improper combustion. Understanding how pressure switches function is essential for maintaining optimal HVAC performance. In this article, we will explore the operation of pressure switches and highlight five top brands you can trust for reliable performance in your HVAC systems.

Understanding Pressure Switches

A pressure switch is a mechanical or electronic device that senses changes in pressure within a system. It is designed to activate or deactivate components based on these pressure variations.

How Pressure Switches Work:

1. Pressure Detection: The switch contains a pressure-sensitive element, often a diaphragm or piston, that reacts to changes in pressure.

2. Mechanical Activation: As pressure increases or decreases, the element deforms, causing mechanical components within the switch to move.

3. Electrical Contact: These mechanical movements trigger electrical contacts to open or close, completing or interrupting a circuit.

4. Component Activation: The change in electrical state can then activate or deactivate various components, such as fans, compressors, or safety devices.
