You need a 1N4004 for the switch diode.

Your other option is to pull the wires out of the connector if you have the pin removal too and then feed them through. A little less of a pain in the backside that way.

I think the easiest way to tell is to just look at the contacts. The tungsten (silver looking) ones are the high voltage/current switches and the gold-plated ones are for low voltage. Also, low voltage EOS switches are typically normally open.

See my picture below, normally open WPC fliptronic switch on the left, normally closed non-fliptronic on the right.

I'm sure 99% of the people who own or would play a HS would even know or care that there is a minor difference between the originals and reproductions. I sure wouldn't care. lol

I'm almost positive that there is a jumper cables from the mpu to the background sound board that connects the two. I can't get at my high speed right now to verify that.
