Rated for over 10,000 cycles, the Viair Bottle Cap Pressure Switch is known for its dependability. An integral component to operate your compressor, this pressure switch will automatically turn on your compressor when the air pressure in your tank drops below the set restart pressure on your pressure switch and automatically shut it off when your air tank reaches the max pressure. The Viair Bottle Cap Pressure Switch works with both 12-Volt and 24-Volt systems, making it ideal for automotive and marine applications! 

We recommend purchasing a relay with this pressure switch when using it with an air compressor. By installing a relay you can alleviate the burden of the compressor from the pressure switch, ensuring an even longer lifespan!
