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