    摘要： Each rotary switch plate assembly consists of a circular base plate, with central perforation for the switch shaft and bushing. The base plate is marked with radiated lines representing the full number of angular switch steps in 360* of switching operation. A circular face plate of transparent plastic and of the same dimensions as the base plate is fastened to the external face of the base plate. The rear surface of the face plate is furnished covered by removable opaque segments of adhesive backed plastic film. The segments of opaque film, representing the actual switch steps employed in a given installation, are removed from the back of the face plate to give visibility to the markings of the base plate governing the segments of operation of the rotary switch of the installation.

    摘要： This invention relates to a rotary, manually adjustable, compact potentiometer suitable for panel mounting and which requires a minimum of behind-panel space. The potentiometer comprises a central mounting assembly including a resistor supporting disc and a manually rotatable hollow knob rotatably mounted around the disc so as to form an enclosed resistor chamber. The central mounting assembly further comprising a flange spaced from the disc, an internal flange in the hollow knob trapped between the disc and the central mounting assembly flange, and an arcuate resistance element mounted in the resistor chamber on the disc. A resilient arm is driven by the knob in the resistor chamber and has a movable contact bearing on the resistance element. Electrical conductors extend through the central mounting assembly to the movable contact and resistance element.

    摘要： The invention provides a composite multiple selector switch, and switch units therefor, for displaying in-line indications of information signals that may be selected by independent manual adjustment of the individual switch units. Each switch unit comprises a stationary switch structure having stationary contacts and a rotary switch structure having rotary contacts which are selectively brought into registry to display a symbol corresponding to the selected information signal. Each of the rotary structures includes a wheel having a plurality of lugs, at least one of which projects at any one time radially outwardly and is accessible through an open window of a switch panel on which the composite switch unit is mounted.
