What Is a Sanborn Air Compressor Pressure Switch?

A pressure switch in an air compressor acts as a safety and control device. It automatically turns the compressor on or off based on preset pressure levels, maintaining optimal operation and preventing damage caused by over-pressurization.

Definition:

A Sanborn air compressor pressure switch is a specifically designed pressure control component manufactured by Sanborn, renowned for its durability, precision, and reliability.

Purpose of the Pressure Switch:

• To control the compressor's motor based on pressure settings
• To prevent the pressure from exceeding safe limits
• To automate the start and stop cycle of the compressor

Key Components:

• Pressure sensing element (diaphragm or piston)
• Electrical contacts to control motor operation
• Adjustment screw to set cut-in and cut-out pressures

How Does a Sanborn Air Compressor Pressure Switch Work?

Understanding the operation of a pressure switch is fundamental to troubleshooting and maintenance. Here’s a simplified overview:

Basic Working Principle

1. Pressure Sensing:

The switch detects the pressure within the tank via a diaphragm or piston mechanism.

2. Pressure Thresholds:

• Cut-in pressure: The pressure level at which the switch activates and starts the compressor.
• Cut-out pressure: The pressure level at which the switch deactivates and stops the compressor.

3. Switch Activation:

When the pressure drops below the cut-in threshold, the switch closes the electrical circuit, turning on the motor.

4. Switch Deactivation:

As the pressure reaches the cut-out threshold, the switch opens the circuit, shutting off the motor.

Visualizing the Process

• The pressure switch is wired to the compressor’s motor.
• Adjusting the pressure settings alters the cut-in and cut-out points, allowing precise control.
