hob ignition

[StewartG]

all of a sudden, all 4 hob ignitions have started to click. I have tried cleaning the switch but it seems OK -

Any one have any idea what else it could be??

all 4 of mine ignite together as they are meant to, as the cooker does,nt know which one you are trying to light.the individual control is by each gas tap
i would say there was a problem before but it has cleared or worse it is intermittent and the ignition leads need replacing as they were arcing out before and not delivering the spark where it was needed
