Standard light switch which also has a spot to store a harbor breeze fan remote. When in prusa slicer, you must add a 4mm tall negative volume on the bottom surface under the switch cutout in order to accommodate the parts of the switch that stick out. I printed out the resulting void with supports which were't bad to remove using a .25mm z distance, but it may work fine using just bridging.
Sand and paint, looks like an injection molded piece.
