Amiga external PSUs - how many types?

[Amigalynx]

The title says it all. Just a pedantic/cultural question. How many types of Amiga PSUs actually existed? I know of four types:

"Power supply A300": switch on the bottom half of the PSU, slightly on the left
"Power supply A600": switch on the upper half, centered
(dunno the designation): switch in the top right corner
"Power supply A500/A600/A1200": the A1200 one, smaller, switch centered on the bottom half

Were there another ones?

@Chain  :-o  you've got some! I'd rather not try this at home, my parents wouldn't appreciate :-D

@motorollin
"Power supply A 300" is just the name labeled under the PSU, I had one with my A600 (maybe this is the explanation, as the 600 was intended to be called 300) and another one with a 500...
