Tact switch replacement U.K

I need to replace a tact switch.
Can anyone recomend a place to get them in U.K?
It's one of the F1-6 buttons under the screan not the bigger Play/stop etc ones.
Could anyone tell me what these are called? I mean, other than Mpc 2000 tact switches, so that I can differentiate between the two types.
I've seen them on ebay, just thought I'd poke about on here for any advice.

ALPS SKHHAKA010

this is the ALPS part number. look for mouser or similiar distributor. when youre on it, change them all. more timeconsuming, but youll have peace for the next 10 years i guess,

Many thanks, G.

no problem.
check mouser/farnell/element14 and so on for parts. these switches will work. the "big buttons" like play, stop, and so on are different switches. just to inform you.
