This hair dryer (from the ’70’s) has the most confusing control labels I’ve ever seen. It takes quite a bit of explaining, it’s so bad.
The hair dryer has two three-position switches: UP, MIDDLE, & DOWN.
Double-MIDDLE = Off. But let’s see how they define & label the nine combinations.
The Left switch (BLUE-GREEN-YELLOW) controls the heat level.
• BLUE (up) = Cool
• GREEN (middle) = Medium, whatever that means (or Off)
• YELLOW (down) = Warm (or Hot, on High Speed)
The Right switch (BLUE-GREEN-RED) controls the air speed.
• BLUE (up) = High
• GREEN (middle) = Low (or Off)
• RED (down) = High
Note that ANYTHING OTHER THAN MIDDLE means high for the right switch.
But it gets worse … Instead of labeling the two switches as “Heat” & “Air”, they label the color combinations, eg: GREEN+RED=“Medium Heat, High Speed.”
Then it gets even worser … they label the Air options (controlled by the right switch) on the left, and the Heat options (controlled by the left switch) on the right. (So in the previous example, GREEN+RED gets labeled “High Speed, Medium Heat”, not “Medium Heat, High Speed”.)
So all of the thought that went into having the switches mean anything individually, gets tossed out the window, and you have to think in terms of meaningless color combinations.
AAAAaaaauuuugggghhh!
Plus: Only seven of the nine possible combinations are labeled. And two of them (“High+Warm” & “High+Medium”) as far as I can tell are synonymous.
MY SUGGESTION
The six combinations (besides OFF) that you need are (Cool-Warm-Hot) x (Low-High). If the switches were labeled (and wired) like this, there’d be no problem & no need for color combination codes.
