I feel really crazy right now:

I am working my way through the APEM 600 series of toggle switches, I found the specs on their site as a pdf (http://www.apem.com/int/index.php?controller=attachment&id_attachment=636))

I found the 644H/2 switch, which they say has the following electrical functions: "on-on-on".

As a double pole, I'd expect it to have 2 rows with 4 contacs each. But it does not

Apparently, you have to wire it in such way, that one lug is connected to the other sites middle lug. But then it is not a double pole anymore. Why do they call it double pole? Why do they say "on-on-on" when it's clearly 2x "on-off-on"?

WTF is wrong with switches and switch-terminology?
