An intermediate layer is coupled to the bottom of the keycap. The intermediate layer is translucent and includes a top and a bottom. The top of the intermediate layer faces the bottom of the keycap. A character layer is positioned between the bottom of the keycap and the top of the intermediate layer. A resilient member is coupled to the bottom of the intermediate layer. The resilient member is translucent and is configured to direct light through the intermediate layer, through the character layer, and out from the keycap. The character layer is configured to be lighted for viewing through the keycap.
