How do you connect a switch with l1 and l2 with com?

To connect a switch with L1 and L2 to COM, first, ensure the power is off. Connect the COM terminal of the switch to the common terminal of your load (e.g., a light or appliance). Then, connect L1 and L2 to the respective terminals on the switch, allowing you to toggle between the two circuits. Finally, restore power and test the switch to ensure it functions correctly.
