Along with what’s already said, here’s some more info.
When the bat button relay closes, switch b on the relay will close pulling in the swing relay.
Swing relay will stay pulled in thru it’s hold circuit.
Switch E on the swing relay closes and enables power to the trough strike switch.
If the trough switch is gapped too close, then vibration from the pitch unit will pull in the strike relay, opening the bat coil circuit and releasing the swing relay hold circuit.
Check and adjust trough switch if needed.
