Everything you should know before buying Hubbell pressure switches

Hubbell Pressure switches are usually linked with Air compressor pumps. Air compressor pumps functions at high temperatures as well as in locations where explosions and fire hazards restrict other form of energy.


To put it in a nutshell, Hubbell pressure switches essentially tell the pump when to turn on and when to turn off. A more technical description of a pressure switch sounds like this: a device that monitors pressure as well as provides an output when a set pressure is reached. The precise pressure that opens as well as closes the switch is called the set point. Numerous pressure switches are intended for a minimum of 30 PSI as well as a maximum of 50 PSI (or pounds per square inch). So in this instance when the pressure in the system drops to 30 PSI, the switch activates and lets more air flow into the system.

Hubbell Pressure switches are comprised of numerous components including an adjustment screw, diaphragm, lever, as well as contacts. The alteration screw sets the air pressure. This can be attuned to change the on-and-off pressure range that the switch operates at. The standard range of a pressure switch is frequently located on the unit itself or on the box it comes in. You can always check online as Air compressor if you know the model number.


Pressure switches depend upon air pressure to do all the work. The change in pressure that activates the switch is offered by means of the air from the surrounding. The pressure moves up through the diaphragm which presses against a piston as well as spring, which in turn opens or else closes the contacts.  Open contacts situated within the switch, closes when pressure drops. This completes an electrical trail, which in turn activates the pump. When the set pressure is reached, this permits the contacts to open again which turns off the pump.

Pressure switches are typically wired to a control box. Wires from the box are associated to separate terminals within the switch while other terminals are associated to a power supply. If you are looking for such highest-quality pressure switches, consider buying from Emergency Sales and Service
