If you are talking about the switch stack at the end of the bonus ball rack, here they are. Note that Super Soccer and 300 used different switch assemblies.

There is supposed to be a long, U-shaped wireform in the track that pushes down on the switch. When one or more balls are at the gate on the far left side of the track, they push down on the wireform, which actuates the switch. There's a pic on IPDB where you can see the wireform fairly well through the backglass:

That's what we like to hear!
