Load box Construction

Hello guys!
Sorry to bother. I originally posted this question on the pioneer forum, but when I looked around the site more it became clear it would be better to post it here.


I have been having trouble building a load box schematic from a pioneer manual. I'm gonna copy the original post I made in hope someone can help me.

"On page 32 of the first tuning fork guide, the manual shows the schematic to a load box, which I decided to build, but the circuit has me puzzled by some of its components.

The components list is nothing out of the ordinary, but i dont have the single idea what a “ switch Siemens type” is, and by researching this switch on the internet only brings a brand specialized on the production of internet cable connectors of the same name.

I think these switches are the ones represented in the diagram by Monitor S3-1 and S3-2, but I'm not sure. (I have a feeling these 2 parts are either some kind of audio jack, because the symbol is similar to a p2 audio jack schematic symbol, or maybe a 3 position 12 pin lever switch).

If someone could forward some information about the switch, or an updated version of the diagram I would be very thankful.

You got me as well, I could guess that you want a switch with silver plated contacts for high current applications
 
Looks unnecessarily complex to me but that's not really the question. ;)

To me it looks like S3 is (or could be) an On-Off-On 4PDT switch.
