10 best pressure switch for air compressor 120 150psi

A pressure switch for an air compressor, specifically one rated for 120 to 150 PSI, is an essential component that helps regulate the operation of the air compressor. Here's what you need to know about it:

Function: The pressure switch serves as a control device for the air compressor. It monitors the air pressure inside the compressor tank and activates or deactivates the compressor motor based on preset pressure levels. In the case of a 120-150 PSI switch, it will turn the compressor on when the tank pressure drops below 120 PSI and off when it reaches 150 PSI.
Pressure Range: The pressure switch you mentioned has a specified pressure range of 120 to 150 PSI. This means it will engage the compressor motor to build air pressure when it falls below 120 PSI and stop the motor when it reaches 150 PSI. This range can be adjusted within certain limits to suit your specific needs.
Safety and Efficiency: Pressure switches are crucial for maintaining the safety and efficiency of an air compressor. They prevent the compressor from running continuously, which could lead to overheating or damage to the compressor components. Additionally, they ensure that the air pressure remains within a safe operating range.
Adjustability: Many pressure switches are adjustable, allowing users to set the cut-in (start) and cut-out (stop) pressures within a specified range. This adjustability allows you to tailor the compressor's operation to match the requirements of your tools or applications.
Installation: Installing a pressure switch typically involves connecting it to the compressor's tank and motor. It often includes electrical wiring to control the motor.Proper installation is crucial to ensure the switch functions correctly.
Maintenance: Pressure switches require periodic maintenance to ensure they continue to operate reliably. This may include checking for air leaks, inspecting electrical connections, and cleaning or replacing components as needed.
Compatibility: When replacing a pressure switch, it's essential to choose one that is compatible with your specific air compressor model and meets the pressure range requirements.
Safety Features: Some pressure switches come with additional safety features, such as an unloader valve. This valve releases air pressure from the compressor head after the motor stops, preventing it from restarting under load, which can extend the motor's lifespan.

In conclusion, a pressure switch for an air compressor rated for 120 to 150 PSI is a critical component that regulates the operation of the compressor, ensuring it operates within a safe and efficient pressure range. Proper installation, adjustment, and maintenance of the pressure switch are essential for the reliable operation of the air compressor.

User questions & answers

Question:	Can it be used on 120V
Answer:	Yeah it should. It's simply air pressure actuated contacts. If anything it can handle 120v easier
Question:	can this be used with an on board air compressor on a jeep wrangler
Answer:	Ignore the ignorance. It is rated up to 220v AC but can easily be used for 12vdc but a simple 12vdc non-mechanical switch would be more economical on a vehicle.
Question:	Does this have a unloader valve attached to the pressure switch
Answer:	It does not have an unloader valve.

User questions & answers

Question:	What does 40psi fixed differential mean? I want it to turn on at 100psi off 175psi
Answer:	Differential is the spread between cut on and Cut off. So if you have it set Off at 175 psi it would cut in at 135 psi. You will need to consider a different type of switch for a 75 psi differential.

User questions & answers

Question:	Will this work on water and does this have a low pressure cut auto cut off
Answer:	I think it will work as a control switch for water pump. The pressure setting is determined by manufacturer, so be sure to order the right switch, per the needed pressure limit of your system.
Question:	Will this work with a 6 horse 220 motor
Answer:	Check the amp rating on this switch with the amp rating on your motor. If the witch is rated higher then the motor it should work. If not it will burn up at some point.
Question:	The points on the one I ordered started sticking within days of installing
Answer:	Dear Sirs, first unplug power from the unit. Do not want to get shocked. Get a flat finger nail file and clean the surface on the contacts. Open up the contacts, place the file in between the contacts and use the pressure of the springs to clean the contacts. If you have contact cleaner, brake cleaner spray down the unit and let dry. If you have reserve air, blow the unit out. This should fix the problem. If not look to see if you have a malfunction or something sticking else where to prevent the unit from working properly. Good luck!
Question:	Will this work on 220 volt 6 horse motor? Thanks
Answer:	Yes I got one on a 220 volt 6.5 HP
