Why Does Switch Amperage Matter In Air Switches?

Switches are not over current devices but control devices, meaning that switches are rated for the load they are controlling, not the size circuit they are on. By increasing or decreasing amperage and grams of force, you are able to control how sensitive the microswitch within your air switch is to the pressure it is being exposed to. If you have questions about which amp switch is right for you, contact us.

Air Switch Amperage

Dictionary.com defines amperage as “The magnitude of an electric current measured in amperes, esp the rated current of an electrical component or device”

Now in order to understand amperage, you also need to be able to understand volts. According to Dictionary.com, volts are “The standard unit of potential difference and electromotive force in the International System of Units (SI), formally defined to be the difference of electric potential between two points of a conductor carrying a constant current of one ampere, when the power dissipated between these points is equal to one watt.”

So what do all these definitions mean? Essentially, amps measure the volume of electrons flowing while volts measure the pressure that is causing them to flow.

When it comes to presair air switches, we offer several different switch amperages.  By increasing or decreasing amperage and grams of force, you are able to control how sensitive the microswitch within your air switch is to the pressure it is being exposed to. By going down in amperage and the required grams of force needed to actuate the microswitch, we are able to actuate an air switch up to 100ft in length away from the control box.

Low Pressure Sensing Air Switch – 5 Amps for Long Distance Tubing 

The Presair Air Switching system uses an air bellow actuator joined by tubing to an air switch contained within the equipment or appliance to be switched. Pushing the actuator creates enough pressure to operate the air switch which safely controls the equipment. There is complete electrical isolation with no voltage – low or high – to worry about at the point of actuation. No external compressed air is required.Tinytrol Pressure Switch

The Tinytrol air switches are miniature single or double pole alternate action & momentary action air switches. Typical distance between Presair actuators and Tinytrol air switch for alternate action is 20 feet, for momentary action distances of tubing up to 35 feet. Distances of 100 feet are available, please consult factory for more information.
