I forgot to unplug it…

In this article, we’re going to answer if irons turn off automatically or not and what happens if you forgot to unplug the iron.

Will my iron turn off automatically?

Irons with auto-shutoff feature comes with relays and sensors to shut off automatically. The automatic shut-offs turn off power to the sole plate heater when the iron has not been used for a fixed period of time.

The first switch located on the iron’s handle is closed when the iron is held by a user. A second switch located on the iron’s heel is closed when the iron stands in the upright position.

Some automatic shut-offs use two separate timing periods to determine when power should be removed from the soleplate heater.

A first timing period is selected because iron is often left in a resting position on its heel while it is in use but the user is attending to related tasks, such as folding or hanging clothes.

During normal use, it may be left in this position for a relatively long period of time, perhaps 10 or 15 minutes. Thus, it is desirable to have the automatic shut off’s timing period at least this long.

According to a patent,

The present invention relates to an automatic shut off for a clothes iron and more particularly to an automatic shut off having multiple switches. One switch prevents the automatic shut off timer from running while another switch controls the timing period of the automatic shut off.

How auto shut off save electricity & clothes burns?

Modern irons come with auto shut-off features having temperature sensors and gravity-based switches. When the iron is left untouched for a certain period of time it will start to reach its max temperature and the temperature sensor trips thus cutting off the power supply to the heating element of the iron.

When placed in vertical mode, the gravity-based switch gets activated and the circuit board will cut off the power supply after a certain amount of time.

Is it recommended to leave your iron plugged in?

If you intentionally leave your iron plugged in, then you’re doing it wrong. By turning it off, first, it will save electricity, and second, it’ll reduce the risk of voltage overload.

These irons, hair straighteners, dryers draw a huge amount of ampere. While the models will not catch on fire but their circuits and wires can cause short circuits after a certain period of misuse.

If you forgot to turn it off by mistake on a rushed morning then it is fine but as a responsible person you must check all the electrical connections like fans, lights, and other kitchen & grooming appliances, and turn them off.
