How to Make Continuity Tester
A continuity tester is an item of electrical test equipment used to determine if an electrical path can be established between two points, that is if an electrical circuit can be made. The circuit under test is completely
de-energized prior to connecting the apparatus.
How do you test continuity on a light circuit?
Connect one probe to the hot wire or terminal of the switch and the other probe to the wire or terminal that goes to the light fixture. Turn on the switch and observe the light bulb. If the light bulb lights up, it means there is continuity and the switch is working.
