摘要:
A light pipe structure for a dimmer switch comprises a continuous status indicator lens and a plurality of light pipes, which are operable to conduct the light from a plurality of discrete sources to the lens. The light conducted from one of the discrete sources through a light pipe generates a pinpoint of light on the front surface of the lens. The pinpoint of light is surrounded by a diffusion of light across the front surface of the lens, which produces an aesthetically-pleasing effect by increasing the uniformity of the illumination across the front surface of the status indicator lens. The light pipes are coupled to the lens via a plurality of rounds, which provide for diffusion of light around the pinpoint of light on the lens. The light pipes may comprise light-refracting structures, which the amount of light emitted from adjacent discrete sources from reaching the front surface of the lens.

A load control device, for controlling the amount of power delivered to a electrical load from an AC power source, comprises a user interface adapted to be received in an opening of a traditional-style faceplate and providing a plurality of functionalities on a single control button. A transitory actuation of the control button controls the power delivered to the load. Pulling the control button away from the load control device actuates an air-gap switch to provide an air-gap break in the electrical connection between the source and the load. A linear array of status indicators is provided on a front surface of the control button and displays a visual representation of the amount of power being delivered to the load. A plurality of light pipes are provided inside the control button to conduct the light from a plurality of light-emitting diodes to the front surface of the control button.

摘要:
A push/pull switch control is incorporated into the surface pattern of a wall box dimmer having a planar face surface. The switch control is finger nail operated and contains a finger nail groove which is accessible on the bottom end surface of the operator so it can be withdrawn to an open position. A switch position indicia is exposed when the operator is withdrawn. The notch is preferably curved with the cross-curvature of the human finger nail
