They are two switches indeed, but from what i've seen you'll get sent an EOS switch with tungsten tipped contacts and an ordinary switch attached.

You need 2 pairs of tungsten tipped switches as the second switch operates the smaller upper flipper.

So you need a flipper switch and an EOS switch.

I haven't found anyone that sells the correct setup and have had to buy 2 switches and modify them to fit.

You need the switch with the nylon lug because as the crank rotates it opens the EOS switch then the switch with the nylon lug that rests against the EOS switch closes the top flipper switch.
