Just looking it over it's the trigger circuit, but I guess you knew that. What exactly do you need to anser about it?
While they call S1 a "silicon power cube", the diagrammatic symbol is that of a transistor. Looks to me like the circuit in the red is using a switch to apply a voltage to the transistor which then closes (switches on) the high-voltage part of the circuit to energize the coil & fire the projectile. This strikes me as analagous to using a relay in order to switch high-voltage/current circuits with low voltage/current circuits.
Hope that helps.
