Which is exactly why I would say the one you linked to is Not Suitable.

As usual, Amazon won't tell you little things like whether you can use it or

"As with pretty much all dimmer switches, the ground side is switched rather
than the positive side. So you must hookup the output ground wire to your
LEDs."
