Just started watching the following video, where it is claimed that the plastic bit in the string of pull cord switches is for insulation purposes and thus is a safety device.
I can understand this if true, although is new news to me. Any truth to this, have you heard this before, and is there...
Hi,
I recently had a new cooker switch installed, the day after he installed it the red light on top stopped working. I am slightly worried there may be a loose wire; the cooker still powers up so the switch is doing it’s job. Should I be concerned or is it most likely to be just the bulb?
