## Description

Horizon TBS-301 Single Pole Double Throw 25 Amp Air Switch - 59-319-1700

Review: Fixed my insinkerator air switch - If you have trouble with your insinkerator brand air switch, this is the part that likely needs to be replaced. My counter top mounted disposal button sometimes collects water and it eventually goes down the air tube and can effect the electrical components. I swapped out the switch inside the housing and this fixed my problem of the disposal not turning on/off properly.
Review: Part fit - Had to replace this switch on my septic tank. It is doing the job

If you have trouble with your insinkerator brand air switch, this is the part that likely needs to be replaced. My counter top mounted disposal button sometimes collects water and it eventually goes down the air tube and can effect the electrical components. I swapped out the switch inside the housing and this fixed my problem of the disposal not turning on/off properly.
