"But how does that switch change from open to closed?"

It sounds to me that maybe you are looking for the ‘prime mover’ in all of this which is the program. The program counter is a register that is initialized at reset to point to a specific memory address in the PROM that contains the BIOS which is the first series of instructions to be executed. Each instruction consists of the 1s and 0s that start the avalanche of switching to begin. At the end of the instruction the program counter is either incremented to the next instruction or changed to point to another memory location and begin on that instruction.

Is this closer to what you mean?
