Final answer:
A simple start/stop push-button control circuit requires a minimum of three wires: two for the control circuit and one as a common wire.
Step-by-step explanation:
The minimum number of wires required between start/stop push-button controls is three. In a simple start/stop control circuit, there are typically two wires used for the control circuit itself and one wire used as the common that is connected to the neutral of the power supply. A simple start/stop push-button control circuit requires a minimum of three wires: two for the control circuit and one as a common wire.
It is worth noting that this is a simplified representation and that the actual number of wires can vary based on the complexity of the system, whether it includes relay logic, safety interlocks, additional controls, and so forth.
