Why AST Microwave?

AST Switch

  • Every AST switch comes sealed as a standard.

  • Our motor is inside the aluminum switch head between 2 seals so no moisture can penetrate.

  • Every AST switch is tested under water.

Other Manufacturers

Offer sealed and unsealed versions of their switches. They use a plastic "can" to cover & seal their switch. If you have to operate the switch manually & remove the protective cover, humidity could potentially damage the motor.

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.
