Ah yes, the dreaded prop interruptor switches!!
Yet another retrofit to sort out problems with the prop de-icing IIRC. Unfortunately they required reselection/deselection when using reverse thrust and if you got it wrong you were stuck in reverse. Needless to say, such a potential 'Murphy' didn't take long to surface - one of the early 30 Sqn aircraft was being parked in a dispersal, at Dishforth, using reverse thrust but with the switches deselected - dispersal sloped down in the direction of travel.... attempts to get out of reverse failed and subsequent brake application produced the inevitable rotation onto the tail
Happy days
