Yes, too much confusion; there is good reason for agreed upon standards, but ...
If only there were fewer standards — electrical plugs , bike BBs, computer connections etc — the number of "standards" in the world drives me nuts. The diagrams above don't even show all the standards that exist, just the common ones...
Hmmm good name for a pedal: "Standard General" for a generic OD or ...
In post #2, the switch in the diagram seems numbered backwards to what I usually see, which doesn't matter too much 'cause if you rotate the switch 180 the lugs will be in the "correct" numbered positions (looking at the lugs on the bottom of the switch):
1 4
2 5
3 6
However, if somebody doesn't pay attention to the diagram and then thinks of upper left corner when told to connect blah-blah to lug "#1", when in fact connecting blah-blah to lug "#1" is based on that datasheet's backwards diagram...
Every on-on-on switch I've ordered from Tayda is a DPDT Type 1, including the type 2 ordered from Tayda — when the type 2 arrived it turned out to be a type 1:
Cracking it open to mod it, if you simply
spin the internals of your on-on-on switch 180º, you still have a type 1:
As mentioned in my first post, somebody told me how to do it and so I pulled apart a type 1 switch and
flipped the little internal jumper-kajigger:
Boom, type 2 at last with lugs 2&3 and 4&5 connected.
Reassembled it a number of times until the switch's internal bits were aligned inside for smooth operation and it worked as it should.
Fingers crossed for your Musikding switch!
