What happens here

To test a light switch, attach the multimeter probes to the two main terminals of the switch. When the switch is in the 'on' position, the multimeter should beep, indicating continuity (a closed circuit). When you flip the switch to the 'off' position, the beep should stop, indicating an open circuit (no continuity). If the switch fails to beep when 'on' or beeps when 'off', it may be faulty.

Goal: Check the operational status of a light switch.
