No power to light switch

[John4nikki]

Hi my kitchen light suddenly stopped working. I have tested the wires into the switch and they are dead, the loop in the ceiling is fine. Don;t think it's breaker related as it just the switch, just wondering if I have missed something before calling in an electrician. Thanks

Assuming it’s not the light bulb the wires into the switch or the pendant might be loose. Are other lights in the same circuit working.

How have you tested, and what output?

 

[ericmark]

In the main, if not the bulb, then a screw has worked loose and you have a bad connection, or switch faulty, so slight tug on each wire, and test switch.

However there are exceptions, my landing light has a Smart relay in it, and the voltage to switch is extra low, I think this is unlikely, but there are exceptions.

Hi thanks for the replies, I have removed the light switch and tested the wires that directly run into the switch they are dead. Light will work off the loop but would be permanently on Cheers

Is the switch cable fed from a ceiling rose ?
What are you using to measure voltages present at the switch ?

 

[John4nikki]

Hmm not sure, got me thinking I will test all the ceiling wiring just to double check. Loop is live, switched wire is dead, I have a multimeter for testing Cheers

 

[terryplumb]

At the switch wiring ,where exactly are you placing the multimeters probes ? One probe touching a conductor connected to a switch terminal ,what is the other probe touching ?

 

[John4nikki]

Hi probes test on both connections as shown in pic cheers

 

[John4nikki]

Also existing wiring on the rose

 

[terryplumb]

It appears that you are connecting to two line conductors ?That is not how to measure voltages.

Am I missing something?

 

[terryplumb]

What is the cable at the ceiling that has red and black conductors ,each in seperate connector blocks , not connected to anything else ?

 

[John4nikki]

The red and black connections were wired to the light fitting, I have taken it light off for testing and picture purposes. Can you tell me what connections need to be test on the light switch please. Cheers

 

[terryplumb]

Are you sure those 2 ( red and black) wires connected directly to the light fitting ?
Is the light fitting one of two That works from the same switch ?
