Why is 切 on microwaves instead of 分?


I've noticed that the microwave minute dials often use 切 instead of 分 for
minutes. Why is this the case?

When I look up [切 on jisho](http://jisho.org/search/%E5%88%87%20%23kanji), I
get nothing about time or minutes, so I'm naturally confused as to why I
always see this.

Here's a picture:

Thanks!




切る means 'to cut off' or 'to turn off', and it's likely used here to mean to
turn off the power and finish using the microwave.
