2.Attach an ohmmeter to the black and white wires. The meter should read infinity with the magnet away from the switch.
3.Bring the magnet toward the switch until the meter reads zero ohms. Mark this position.
4.Bring the magnet closer to the switch until the meter reads infinity. Mark this position.
5.Position the magnet between the two marks.
6.Align the magnet and switch so the labels read in the same direction. With the magnet positioned in this manner, the switch will be harder to defeat with an external magnet.
