Patent Images
1. An illuminated vanity mirror assembly including a variable resistance circuit for providing a dimming control comprising:
- an electrical circuit board having a resistance material extending along a predetermined length of one side of said board;
electrical contact means for selectively engaging said resistance material;
means for mounting said circuit board and said contact means for movement relative to each other to provide a variable resistance to said contact means; and
means for electrically coupling said contact means to lamp means associated with the vanity mirror for selectively varying the intensity of light from said lamp means.

Abstract
A dimming control circuit for use in an illuminated vanity mirror includes a surface formed variable resistor on a circuit board and wiper contacts engaging the resistor. One of the resistor or wiper contacts is movably mounted to a mirror frame with the other of the resistor or wiper contacts being stationary such that the resistance can be varied to control the light intensity.
