How to use a multimeter to test a light switch. Test a Light Switch With a Multimeter - YouTube. BZ PHS ANGLE 5Fixed. If playback doesnt begin shortly try restarting your device.

After you are sure that there is no electrical current flowing anymore take out the light switch by the frame separate the switch from your house wires lose the terminal screws just enough so that you can remove the wires that are attached. In this article I have briefly discussed how to use a multi-meter to test a light switch. Testing the switch for the continuity.

With your multimeter touch all the tester probe to any other screw terminal. After doing this turn on and off the light switch and when it is on the reading should be near to zero. Nevertheless when the light switch is off the reading shown should be 1 which means no continuity.

I show how to use a multimeter and voltage tester to troubleshoot a light switch circuit box and light bulbs. Very easy way to test light switch with multimeter. Make your to turn the power off at your breaker.

Find a live working outlet place the probe end near the smaller opening for the plug thats the hot side. The probe should light up and make a noise. You dont need to touch anything just get with in an inch or so.

Turn off the circuit breaker that delivers power to the light switch being tested. Uninstall the light switch. Turn on the multimeter and put it on the Continuity or Ohms setting depending on the model you have.

There are two ways to check a light socket with a voltmeter. The first is to check the voltage. You can do this with the power on and the bulb removed.

The second way is to test continuity or resistance. For this test the power must be off and the light fixture disconnected from the circuit. How to Test a Switch With an Ohm Meter.

Verify ohm meter operation. Turn on the multimeter. Insert the leads into the meter Touch the probe tips together to verify that ohm meter is functioning.

Connect the red lead to one of the terminals on the switch. Put the switch into the OFF position. Operate the switch on and off for a few more times.

Connect the leads to the two terminals and then apply pressure to the brake light switch. On the ohm scale it will go from open to an ohm maybe half an ohm depending upon the connection and internal resistance. Put the negative lead from the test probe to one terminal from a diode and put the positive lead from the test probe to another terminal from the diode.

The multimeters screen will display the precise voltage reading. Connect the red lead to one of the terminals on the switch. Connect the black lead to the other terminal on the switch.

Put the switch into the ON position. The meter should display 1 ohm or less meaning the switch is ON. If youre using a multimeter set the instruments dial to the continuity or resistance setting then touch one tester probe to the common dark-colored terminal and the other probe to one of the traveler terminals.
