ABSTRACT:
A display apparatus for illuminating a switch is provided which includes a switch having an on and off position to control power from a power supply to a device. A light source is located near the switch to illuminate the switch. A diode is electrically connected between the on position of the switch and the light source. A first resistor is electrically connected between the off position of the switch and the light source. The first resistor is electrically in parallel with the switch and the diode. When the switch is in the off position, power is provided to the light source via the first resistor whereby the light source illuminates at a first brightness. When the switch is in the on position, power is provided to the light source via the diode whereby the light source illuminates at a second brightness which is greater than the first brightness. Thus, the light source is always illuminated to facilitate locating the switch, and the light source illuminates brightly when the switch is on so that a person can quickly determine whether the switch is in the on or off position.
