If there are a lot of wires in the electrical box and you're not sure whether the malfunction is due to a wiring problem or a faulty switch, you canuse a voltage testerto test the switch. You need a tester with two leads, not a non-contact one, for this test. To perform the tes...
A digital multimeter’s Continuity Test mode can be used to test switches, fuses, electrical connections, conductors and other components. A good fuse, for example, should have continuity. A DMM emits an audible response (a beep) when it detects a complete path. The beep, an audible indicato...
