There are 2 types of 5 way blade switch, the one fitted by most manufacturers is a 2 pole 5 way (however it is really a modified 3 way with the 'in between settings' added). You can tell this type because it has 4 connectors on each side (if it is the CTS/Switchcraft version), the japanese version has 8 connectors in a row with a gap between 4 and 5.
The 4-pole 5-way has 24 connectors. They are arranged in 2 banks of 6 on 2 separate wafers (there is a Yamaha version which just has the connectors showing, not the wafers, but it is the same). I don't know of any manufaturer other than PRS and Yamaha who use these as standard.
