Air Pressure Switch 70 - 100 PSI Pressure Switch 1/4"-18 NPT 24V 12V Pressure Switch Air Compressor Pressure Switch 100PSI Pressure Controller 70PSI Low Pressure Switch

Built my own onboard air system in my Jeep these worked perfectly to attach to the air tank to prevent it from over inflating probably should have gotten one that was a little higher but seems to be working great so far.

The Air Pressure Switch 70-100 PSI is designed to regulate air compressor pressure within a specified range, providing efficient control over pneumatic systems. Here's a comprehensive review: Precise Pressure Regulation: This pressure switch is calibrated to activate when the air pressure within the system reaches the preset range of 70-100 PSI. By automatically turning the compressor on or off at the desired pressure levels, it ensures consistent and reliable operation of pneumatic equipment. Universal Compatibility: With a standard 1/4"-18 NPT thread size, this pressure switch is compatible with a wide range of air compressors and pneumatic systems. It offers versatility in installation and can be easily integrated into existing setups without the need for additional adapters or modifications. Voltage Options: Available in both 24V and 12V configurations, this pressure switch accommodates different power requirements and electrical systems commonly found in automotive, industrial, and residential applications. Users can choose the appropriate voltage option based on their specific needs and equipment. Durable Construction: Constructed from high-quality materials, including rugged brass and durable plastic components, this pressure switch offers long-lasting durability and reliability in demanding operating conditions. Its robust construction ensures resistance to corrosion, pressure, and temperature variations, ensuring consistent performance over time. Easy Installation: The pressure switch features a straightforward installation process, allowing users to mount it securely onto the compressor tank or manifold using the 1/4"-18 NPT thread connection. Its compact size and lightweight design facilitate easy placement and integration into pneumatic systems. Wide Range of Applications: Suitable for various pneumatic applications, including air compressors, pneumatic tools, pressure washers, and HVAC systems, this pressure switch offers versatility and adaptability to different industries and use cases. It provides precise pressure control, enhancing the efficiency and performance of pneumatic equipment. Reliable Performance: Manufactured to high-quality standards and subjected to rigorous testing, this pressure switch delivers reliable and consistent performance in controlling air compressor pressure. Its accurate pressure sensing mechanism ensures precise operation, minimizing the risk of overpressure or pressure fluctuations. Overall, the Air Pressure Switch 70-100 PSI offers precise pressure regulation, universal compatibility, voltage options, durable construction, easy installation, a wide range of applications, and reliable performance, making it an essential component for maintaining optimal air compressor operation and pneumatic system efficiency.

Fixed it

Works perfect. Kicks on at the right pressure. Kicks off at the right pressure.

Pressure Switch works ok but not quite at the rated PSI. I put an old style round liquid filled PSI gauge on the line and saw that the switch activates (opens circuit, is NC) at 95 PSI, and has a quick hiccup at 69 psi, then actually closes the circuit at 65 PSI. Totally fine for my purposes, but not exactly as advertised. But it is within 5 PSI. I added this switch to control a portable air compressor for airing up Jeep tires when we get back to pavement. Having the pressure switch stop the compressor saves a lot of wear on the compressor & hoses. No need to manually turn the compressor off between tires anymore, now it will do that by itself. This psi switch will def NOT handle the full current of an air compressor. THIS SWITCH CAN HANDLE 10 AMPS MAX. MAYBE LESS. USE A RELAY. Our compressor pulls more like 15 amps, and someone else stated in the reviews that they blew up their first psi switch on their Jeep air compressor, then they added a relay & then it was fine. During this project, I learned that for this kind of load, the trick is to use a relay with stud terminals like this one has. I first tried a 30 amp relay with connectors & wires included. Those wimpy little 4 or 5 wire connectors on the 30 amp relays are just too weak & too small to take the load. The load wires to the 30 amp relay got hot & the connector started smoking. Nope! Not ok! I replaced that 30a relay with a 120 amp relay with stud terminals & it's fine now. I used the: [Hamolar 2 Pack 12V DC 120A Starter Relay Switch Car Heavy Duty Split Charge Continuous Duty 4 Terminal SPST Relays for Truck Boat Marine] https://amzn.to/3JR5dFX Cost was a little more per relay, but necessary & better. Anyway, this pressure switch is fine, even if it is off by 5 psi. NBD.

….but I can’t verify the accuracy yet. My gauge shows 65-90 so I don’t know it the gauge or the pressure switch is off a bit. I’ll get a better idea and once I do I’ll update this review. It does turn on and off consistently though.

Nice

Nice cheap pressure switch that doesn't go up to 100 like it's supposed to, not a problem for me, but might be for someone.

Used to replace a failed pressure switch in my truck for my onboard air system. Has worked flawless since install

Bought this for a specialized machine retrofit, cuts in at 70 cuts out at 100, perfect.

bought a 2 pack because I didn't think they would last and I am still on the first one.

I replaced a big bulky one with this and it works perfectly. I am using it on a small onboard compressor system

Bien, utilisé pour mini compresseur de 3 litres, je passe le pressostart par un relais.
