[ re grid switch type components ]

Probably best to nip down your local electrical wholesaler, they'll
have the bits on the shelf and will know what you're on about.

The strange thins is, if you want MK you might have better luck going to B&Q
!

All four of my local trade electrical factor don't stock (but can order) MK
grid components, B&Q have most of the common parts on the shelf - go
figure...
