Shower switch etc

[the pict]

We all know what a phaff getting these and cooker switches in, the problem as I see it is this with this type of load device the screws are never accessable without screwing the assembly round or tilting it thus straining the terminations you have already made even if you do the "difficult" ones first,the back boxes in almost all cases need "modifying" even if you use the deep ones, never have I managed to completly maintain the pvc sheath within the enclosure,what is needed is the manufacturers to address this with application specific accessories,top entry cable terminations switches are easier but perhaps two screws at 90o to each other would help and yes the switch would be a bit bigger and the box also but so what,So people what solutions have you found
