Liquid Level Control Switch
[FSW1]

Just a note about the switch design and function. The product description states "For cutting off the heating circuit when liquid level is low, the sensor tip should be mounted upwards."

Mounting the switch so that the float points up really complicates the installation of it. A much easier way is to mount the switch so that it points down for either fnction. Then simply remove the bottom 'C' clip and then flip the float and reinstall the 'C' clip. This changes the N/C switch function to a N/O switch function.

I hope this makes sense and helps.
