Thats not a switch mate.

THIS IS A SWITCH

Sometimes things you buy online don't come in as you expected them.  Take the above switch for example.  It is intended for switching resistors in a speaker level crossover and I found them for $15 each.  They are electroswitch and have 10A contact ratings and i'm going to give them a shot even though they are a bit larger than I expected.  One thing is for sure,  making an adjustment will really give you a sense of accomplishment.  My favorite part is the little cloth bag holding all of the hardware.  The closest electroswitch I could find was around $250 from digikey and are about 1/2 the size of this beast.
