Air compressors are essential tools for various tasks, from inflating tires to powering pneumatic tools. But even the sturdiest compressor relies on a crucial component: the pressure switch. This small but vital device controls the compressor’s on/off cycle, ensuring it starts when pressure drops and shuts off when it reaches the desired level. Understanding how to wire an air compressor pressure switch is key to maintaining your compressor’s efficiency and longevity. This comprehensive guide will walk you through the process step-by-step, helping you safely and effectively wire your pressure switch.
1. Understanding Your Air Compressor Pressure Switch
Before diving into the wiring process, it’s crucial to understand the components and functions of your air compressor pressure switch. This device typically has two adjustable pressure settings: the cut-in pressure (when the compressor starts) and the cut-out pressure (when it stops). Understanding these settings is paramount for setting the correct pressure for your compressor and avoiding problems such as overpressure or frequent cycling. The switch itself houses several terminals, usually marked for easy identification (L1, L2, C, and sometimes S). A schematic diagram, usually found on the switch itself, will be your map for wiring.
Identifying Terminals and Connections:
- L1 (Line 1): This terminal receives power from your electrical supply.
- L2 (Line 2): This terminal connects to the compressor’s motor.
- C (Common): This is the central terminal that connects to both L1 and L2 depending on whether the compressor is on or off.
- S (Start): Some pressure switches have a separate “Start” terminal to assist in starting the motor. This is often used with larger compressors or those requiring higher starting amperage.
2. Gathering Your Tools and Materials
Proper preparation is crucial for any electrical task. For this project, you will need:
- Screwdrivers (Phillips and flathead): For removing screws and securing wires.

- Wire connectors (crimp or twist-on): For secure wire connections.
- Multimeter (optional): To test the continuity and voltage.
- Your new or replacement pressure switch: Make sure that it is rated for your compressor’s voltage and amperage.
- Your air compressor’s wiring diagram: This is essential for understanding the existing connections.
3. Safely Disconnecting the Power Supply
- Turn off the power: Before you begin, always disconnect the power supply to your air compressor. This is crucial for safety and preventing electrical shocks. Turn off the breaker or unplug the compressor.
- Unplug the compressor: Ensure the connection is safely disconnected from any power source to avoid accidental activation during work.
4. Wiring Your Air Compressor Pressure Switch: A Step-by-Step Guide
This section focuses on the typical wiring configuration. Always refer to your compressor’s wiring diagram before proceeding, as variations exist between models.
- Identify the wires: Locate the wires connected to the old pressure switch. Note their connection points carefully. Often color-coded, these wires correspond to L1, L2, and potentially S or a ground wire.
- Connect L1: Connect the wire coming from your power source (L1) to the corresponding terminal on the new pressure switch.
- Connect L2: Connect the wire leading to the compressor motor (L2) to the appropriate terminal on the pressure switch.
- Connect C (Common) and S (Start, if applicable): Connect the common terminal (C) and the start terminal (S, if present) according to the wiring diagram. The start terminal is often connected to the run capacitor for a smoother start.
- Ground Wire: Ensure you have a properly grounded system. A ground wire connected to the compressor’s chassis and the pressure switch grounding terminal (if available) will provide additional safety.

5. Testing and Adjusting the Pressure Switch
After connecting all the wires, carefully reconnect the compressor to its power source. Then, turn the power back on. Observe the operation of the compressor. It should turn on when the tank pressure drops below the cut-in pressure setting and shut off when it reaches the cut-out pressure setting.
Adjusting the Cut-in and Cut-out Pressures:
Most pressure switches contain adjustable screws for setting these pressures. Consult your compressor’s manual for specific instructions on how to adjust these settings. Generally, a small screwdriver is used to turn these screws, increasing or decreasing the pressure. Always adjust these settings gradually and monitor the compressor’s performance.
6. Troubleshooting Common Issues with Air Compressor Pressure Switch Wiring
Compressor Doesn’t Start:
- Check the power supply: Is the power source connected and functioning correctly?
- Check the wiring connections: Ensure all connections are tight and secure.
- Test the pressure switch: Use a multimeter to determine if the switch is correctly operating. A multimeter can test electrical continuity and the voltage at different points in the circuit.
- Check the thermal overload protector (if applicable): This safety device may have tripped.
Compressor Runs Continuously:
- Check the cut-out pressure setting: It may be set too high or the pressure switch itself may be faulty.
- Check for leaks in the air system: Leaks will prevent the pressure from reaching the cut-out setting.
- Check the unloader valve (if applicable): A faulty unloader valve will prevent the compressor from shutting off properly.
7. Maintaining Your Air Compressor and Pressure Switch
Regular maintenance is essential for extending the lifespan of your air compressor and pressure switch. This includes periodically checking the wiring for any damage or loose connections and ensuring all connections are secure and properly insulated.
