開關，正轉，關閉，反轉

The 4-pole double throw design makes switching between forward and reverse incredibly smooth on my mini mill setup. It clicks into each position with a reassuring solid feel, and the wiring was straightforward with clear terminals. Exactly what I needed to replace the old failing switch.

Installed this on my mini lathe and the 4-pole double throw action feels solid and precise. The forward-off-reverse positions click into place with no slop at all.

The switch body is a bit stiffer than I expected, but that actually gives a nice, positive click when I toggle between forward and reverse. I'm building a mini mill control box and this 4-pole double throw unit should handle the motor leads perfectly.
