Light switch to quickly toggle power on and off for LED control
That's a recent trend in LED lights; the driver changes to give you different color temperatures or even colors by &quot;coding&quot; it with the switch. You don't need anything special, a standard toggle switch is fine. You flip the switch on for the first level, on and off and back on to change to the second level, on-off-on-off-on for the third, on-off-on-off-on-off-on for the 4th (if there is one). This type typically is NOT suitable for dimming, mine is not. Basically if the instructions do not EXPLICITLY say you can use a dimmer, you cannot.
