How do you connect a float switch?

To connect a float switch, first, ensure that the power is turned off to avoid electrical shock. Identify the float switch's terminals: typically, there are two or three wires (common, normally open, and normally closed). Connect the common wire to the power supply, then connect either the normally open or normally closed wire to the load (like a pump or alarm) depending on the desired operation. Finally, secure all connections and restore power to test the float switch's functionality.
