About Float Switches

Float Switch

Float Switch With Splash Guard

Mount these switches from outside the tank through a threaded connection at the top or bottom of your tank. They activate process equipment such as pumps or motors when the chemical level in your tank reaches the float. Choose the switch with a stainless steel float for durability in harsh conditions.

Switches with splash guard minimize false switch activation caused by splashing liquid.

Vertical-Mount Float Switches with Brackets for Chemicals

Use the included bracket to mount these switches to the inside of your tank. They activate process equipment such as pumps or motors when the chemical level in your tank reaches the float. A splash guard minimizes false switch activation caused by splashing liquid. Choose the switch with a stainless steel float for durability in harsh conditions.
