Example 33


This is my part of my vacuum cleaner. There are two symbols next to a pedal that operates a brush; and I always have to think hard how to put it.

 bad33a    bad33h

To be honest, I always thought that a brush was indicated as lower symbol, and I expected the brush to work like most knobs, pedals and switches do, switch on ‘off’ is off, on ‘on’ is on, like:

 bad33f   bad33g

However, when the control is on the ‘brush’-symbol, the brush is in and the other way around;

bad33a (1)  bad33b  bad33c    bad33i  bad33d  bad33e

Actually, now I think what is depicted is not the brush, but the floor, i.e. a carpet (‘brush-symbol’) or a level (e.g., wooden) floor (rectangle).

 bad33m  bad33l
If the floor is depicted, I’d expect the carpet to be displayed the other way around, like bad33k and not bad33j. Confusing.
