Here I'll google it for you
You'd have to probably get an ohm meter and take a plug and cut and strip the wires, then do some plugging in and measuring.
This switch has 2 sets of contacts, as described in the following pdf as having "2 normally closed switches", kinda like a double throw switch in a way. It looks like the Sena output would go to pins 2 and 5, and normally 2 & 5 are connected to pins 3 & 4 (helmet speakers?). Then when you plug in your earbuds it connects pins 2 & 5 to the earbud wires. You have to figure out polarity which is which.
Are you trying to hook up something that normally connects to speakers in the helmet but when you plug in the earbud male end it then connects only to the earbuds???
If not then maybe the part 24-392-1 looks much simpler. No normally closed connections, more like a single throw switch concept.
