Pressure switches are commonly used for air compressors, gas furnaces, water pumps and other pressure-sensitive applications. They are designed to regulate pressure and provide electrical signals to the control circuit when different pressure levels are achieved. The installation of pressure switches is a simple process. However, understanding the electrical wiring diagrams of pressure switches is essential to ensure a successful installation.
How to Read a Wiring Diagram
Wiring diagrams of pressure switches are represented by symbols, lines and arrows. Each symbol represents a certain part of the switch, such as the power source, the pressure switch itself and the electrical connections. The lines indicate the path of the electrical current, while arrows indicate the direction of the current. To understand the wiring diagram, you must be familiar with the symbols used.
Connecting the Pressure Switch
Once you understand the wiring diagram, you can begin the installation process. First, you need to connect the power source to the pressure switch. Make sure the power source is off during this process. Then, connect the pressure switch to the load. The load is the device that the pressure switch will control. Finally, connect the switch to the control circuit. This will allow it to send electrical signals when the pressure levels are achieved.
Installing pressure switches is a straightforward process. However, it is important to understand the wiring diagrams of the switches. By familiarizing yourself with the symbols and diagrams, you can ensure a successful installation. With a little practice, you can easily understand and install pressure switches for a variety of applications.
