About Pressure Switches
Pressure Switches are an essential tool for a variety of applications. Pressure switches are devices used to detect pressure changes in gases or liquids and then activate or deactivate electrical circuits accordingly. They are often used in industrial settings, but can also be used in residential and commercial settings.
Types of Pressure Switches
Pressure switches come in many different types, depending on the application. For example, low-pressure switches may be designed to detect changes at very small pressures while high-pressure switches may need to detect much higher pressures. Some pressure switches may also be designed with specific materials that can better withstand certain environmental conditions.
How Pressure Switches are Made
Pressure Switches are usually made from a combination of metal components such as brass, steel, and aluminum. These metals provide strength and durability for the switch’s housing and internal parts. Other components such as rubber seals, gaskets, diaphragms, springs, valves, sensors and other components are also typically included in the construction of pressure switches.
Industries that use Pressure Switches
Pressure switches can be found across many industries including automotive manufacturing plants, chemical processing plants, oil refineries and power plants. Professionals working in these industries rely on pressure switches to accurately monitor system pressures so they can make sure their systems operate safely and efficiently.
