What’s Inside a Heavy Duty Float Swtich

What’s Inside a Heavy Duty Float Swtich

A master electrician from down under has created a video that shows what can be found inside a heavy duty float switch.

Raymond of New Zealand takes an angle grinder to a sturdy float switch to see what makes it tick. For this general purpose model, it’s simply a counterweight connected to a microswitch.

Ray also sets up a simple circuit to report the on/off status of the switch with a pair of colored lights. It’ll get the job done for basic liquid level sensing, but lacks the precision and detailed feedback of more advanced float switches.

Check out Ray’s videos for more workshop experiments. Don’t miss the electrically overloaded coconut and the classic brick-in-a-washing-machine gag.
