The switch is operated by a square metal plate which is part of the clutch pedal, if the linkage to master cylinder has ever been disconnected the clutch pedal is free to travel higher and the switch can be pushed too far in, it's a sort of self-adjust arrangement.
If the plate is not operating the switch it's safe to pull the switch pin out (holding the clutch pedal down) with some long nose pliers, it's held within the switch by a spring-clip. Pull it out as far as you can, release the clutch pedal and it'll self-adjust to the correct position.
However, the switch not operating should NOT stop the green CC light coming on. But it's possible, as the CC has never worked, it may work IF it's the switch that's at fault. Others have stated that CC starts working and the light comes on once the stalk has been fitted AND the car has had time to recognise the additional equipment.
All the best
