A soft iron core can function as a switch in an electromagnet system by being magnetized when a current is applied, allowing the electrical circuit to be completed and turning on the switch. When the current is turned off, the soft iron core loses its magnetization, breaking the circuit and turning off the switch.
In a 3-way switch setup where the power is located at the switch, the power can be controlled by connecting the power source to the common terminal of one switch and then connecting the other two terminals of the switch to the travelers of the second switch. This setup allows for the power to be controlled from either switch in the circuit.
