Ignition switch

I’ve been advised that the ignition switch is worn on my standard x reg cool/s. Mainly as when I switch it on I have all the electrics but a small movement of the key and they all go. Is this reasonable and if so how easy is it to replace?
If there is already a post here apologies. Can someone direct me to it as I can’t find it or some other link.
Also what replacement would anyone recommend as all pattern parts are not equal in quality.
Cheers in advance DrM
