Why AST Microwave?

The Competiton

Use a plastic "can" to cover & seal their switch. If you have to operate the switch manually & remove the protection cover, humidity will damage the motor.

As you can see in this picture, water permeated into the cover and shorted out the motor

AST Switch

AST switches come sealed as a standard. Our motor is inside the aluminum switch head between 2 seals so no moisture can penetrate.

All AST switches come with many standard features.  What sets us apart from the competition?



  • Our switches never lose pressure, even with the weather cap removed.

  • When dry air is injected into your system, it permeates into the cavity where the microswitches are housed and keeps all contacts dry. 

  • AST switches can work in 100% humidity.

  • Our switches are Blue Anodized, not painted, for better heat reflection and durability.

  • Quick turnaround.

  • Our switches come with a 3 year limited warranty.
