What is an Air Switch?

What is an Air Switch?

What is an Air Switch? Air Switches are part of our product range here at Herga Technology.

As you may assume from the name, an Air Switch is a switch which is activated by air. A push button can be used to instigate a “puff” or “sip” of air which travels along a length of PVC tubing and activates the air switch. The air switch will turn a device on or off. 

What is an Air Switch used for?

A well-known use for an air switch is a kitchen waste disposal. The push button would be located within the kitchen worktop near the sink, pressing the button would send the puff of air through to the air switch within the disposal mechanism and it would switch on.

Other applications include 

  • Spa Jacuzzi controls
  • Push button shower systems in gymnasiums 
  • Toilet flushes in public toilets  

Why is an Air Switch Used?

Air switches are often used in applications where water is present but needs to be kept away from electronics. The PVC tubing which the air travels down enables the air switch within the electrical device to be activated without the user coming into contact with electronics in a wet environment. This makes it safe for the user to activate the device with wet hands.
