For sale there it is one set of 3 button sliders for the HUNTER DUAL SPLIT DIMMER Knobs and compatible sliders.
Those knobs are NOT compatible with Lutron Skylark dimmer switches.
So, it total, you will receive 3 buttons tops for the sliders on the white color. The buttons work on either side of the slider.
To mount them, you will need to push them down on the slider peg until they click and stay in position.
The hole for the slider it is centered, so, when you mount them it does not matter the side you mount them.
Those sliders are for the Hunter Dual Split Dimmer from the images, but they may work on other models with similar slider peg, but I did not tried them on other models
