Abstract

An electrochromic mirror includes housing, a rearview mirror subassembly including a reflector in the housing, and an electrical circuit with switches adapted to interact with electrical systems in the vehicle. An elongated display area is formed in a face of the housing assembly, either under, aside or above the face. Switch buttons are positioned in the display area for operating switches in the electrical circuit. Where compact display is needed along with the button, the buttons each have a visible portion with a front symbol-forming window that is light-transmissive, and further with a perimeter made of a visible material that outlines and creates a border around the symbol-forming window, and still further with an opaque outer region that contrasts to the visible material. A light source is positioned to direct light toward each window. Each light source is operably connected to the electrical circuit and the electrical circuit is configured to variably energize and de-energize the associated light source when the one switch is activated and de-activated. By this arrangement, the perimeter is visible during daylight with the light source de-activated, and the perimeter and the symbol-forming window are visible during daylight with the light source activated. Also, the symbol-forming window is visible during night when the light source is activated to a low level of light to show the switch in de-activated and is visible during night when the light source is activated to a high level of light to show that the switch is activated.
