Abstract
A central vacuum cleaning system has a motor in a motor housing in a canister with a receptacle. In the motor housing is a motor control circuit with a printed circuit board. The motor control circuit is mounted to the motor housing using a mounting post having a light guide. The mounting post receives light from a light source on the printed circuit board and guides the light through the mounting post to outside the motor housing. The mounting post can guide the light through structural or non-structural elements. The light provides illuminated information messages to a user. The mounting post has a low voltage connection section for receiving low voltage conductors from outside the motor housing. As the motor control circuit is within the motor housing, the motor housing is a motor control housing. The motor control housing can be separate from the motor housing.
