Almost OT: Pushbutton switch latching

Over heere you can easily get single pole, 12 position rotary switches. 
There's a little key plate, retained by the fixing nut, that you can 
insert into different holes in the switch to select fewer than 12 
positions. So you could quite easily have 8 postiions.
