Install the device in place of a standard switch to add convenient fan control with quiet, smooth actuation. Tri-combo and ground screws help allow easyaccesibility and installation.The top and back body are virtually unbreakable, and the device features electrostatic discharge protection, radio frequency interface filtering, and power failure memory. Eaton fan controls are available with color change kits and are compatible with traditional-style or screwless wallplates.
