I have never seen a bus in an electric iron. Normally, the resistance ribbon is riveted directly on the electric cord terminals thru the bimetallic temperature switch.

Bus bars are used in an electric iron as


A. connectors between the thermostat and the element.
B. heat-adjusting resistors.
C. thermostat supports.
D. electrical terminals

Bus bars are not typically used in electric irons. Electric irons usually have a compact design, and the electrical connections inside are usually made using wires, terminals, and soldering. Bus bars, on the other hand, are mainly used in electrical distribution systems or electrical panels to carry and distribute high currents to various electrical loads.

However, if you meant to ask about the internal wiring of an electric iron, it typically consists of a heating element, thermostatic controls, a power cord, and various safety features like fuses or thermal cutoffs. The heating element is usually made of a high-resistance wire that generates heat when an electrical current passes through it. The power cord connects the iron to a power source, and the thermostatic controls regulate the temperature.

If your electric iron is not working properly, there can be various reasons for it, such as a faulty heating element, an electrical connection issue, or a malfunctioning thermostat. In such cases, it is recommended to either consult the user manual for troubleshooting steps or seek professional assistance from a qualified electrician or appliance repair technician.
