A cab having a wheeled carriage fixed thereto is moved between rails on an elevator car frame and similar rails on a wheeled bogey. The ends of the rails are scarfed in a complimentary fashion so as to provide a temporary half-lap joint between the rails of the bogey and the rails of the car frame. Motion is provided by linear motors having active primaries disposed on the car frame and the bogey and passive secondaries disposed on the cab carriage. Motor control is in response to position signals provided by magnetostrictive linear displacement transducers. The cab carriage includes rollers on vertical axes which contact the insides of the rails for guidance. The cab carriage wheels and rollers are disposed in pairs separated sufficiently so that at least one roller and one wheel of each pair is in contact with a full rail as the carriage crosses the rail joints between the car frame and the bogey. Wheels coated with urethane reduce wheel noise and tapers at the ends of the rails provide smooth rail to rail transitions.

The present invention is directed to an illuminated touch button system having a light ring element, a button element located within and surrounded by the light ring element and an array of light emitting diodes. The light ring element comprises a series of individual chambers situated substantially over each light emitting diode in the array. In the preferred embodiment, each chamber includes a set of three light-receiving triangulated surfaces, these surfaces having a series of edges which act to diffuse the illumination of the light emitting diodes. The chambers, in combination with the edges, produce a relatively even, bright light distribution in the portion of the light ring element surrounding the button element.
