I'v never heard that terminology.
I'm a DIYer, my dads a qualified sparks, I worked in B&Q with a qualified sparks and for all I can remember everyone has always called them chock blocks, because you know... they look like blocks of chocolate

I'm quite surprised you've never heard that. Maybe its a regional thing... or something.
I presume then you're also a DIYer?
This is quite an interesting thread, my parents house has a lightswitch that does nothing
