Illuminated two-color selector switch
First Claim
1. In an illuminated selector switch operator comprising a base member having an axial passage, a rotor rotatably received in the axial passage and drivingly connected to a switch operating means for operating a switch in relation to at least two rotated positions of the rotor, the rotor having an axial passage coaxial with the axial passage of the base, the passages being open at their common ends, a light source removably mounted in the passage of the rotor, and an operating knob removably connected to one of the open ends of the rotor for effecting rotation of the rotor and the knob to the two rotated positions, the improvement comprising a lamp shield removably mounted and fixedly received in the passage of the rotor around the light source and having an aperture in an otherwise closed end for directing light from the light source toward the knob, and the knob having at least two translucent portions one of which is positioned to be in alignment with the aperture in a first rotated position of the knob and the other of which is positioned to be in alignment with the aperture in a second rotated position of the knob.

Abstract
The selector switch has two operating positions, indicated by different colors of light. An operator knob having two spaced translucent portions of different colors is drivingly connected to a tubular switch operator rotor. A lamp shield is received within the rotor around a lamp. The lamp shield has an aperture which directs light only through the translucent portion of the selector switch knob directly over the aperture so that the color of the visible light corresponds to a particular operating position of the selector switch knob.

2. An illuminated selector switch including an operator base having an axial passage extending therethrough, a switch operating means connected to said base, a rotor mounted in the axial passage for rotation about the axis of the passage and drivingly connected to the switch operating means for operating the switch in relation to at least two rotated positions of the rotor, the rotor having a central passage coaxial with said axial passage and open at both ends, a light module mounted in the central passage, the improvement comprising:
- a lamp shield detachably mounted around the light module and stationarily received in the central passage of the rotor, said shield having an aperture for directing light from the light module toward one of the open ends of the rotor; and
a translucent operating knob detachably connected to the one end of the rotor for rotating the rotor through its operating positions and disposed directly over the stationary aperture, said knob having at least two different colored translucent portions, one of which is positioned to be in alignment with the aperture in a first rotated position of the knob and the other of which is positioned to be in alignment with the aperture in a second rotated position of the knob, so that as the knob and rotor are corotated, the aperture directs light to pass through only the colored portion of the knob corresponding to that selected operating position of the selector switch. - View Dependent Claims (3, 4, 5)
- a lamp shield detachably mounted around the light module and stationarily received in the central passage of the rotor, said shield having an aperture for directing light from the light module toward one of the open ends of the rotor; and

6. An illuminated selector switch operator having a base with a through lineal passage therein, a rotor means mounted in the passage for rotation about the axis of the passage, said rotor means having a central passage coaxial with said lineal passage, a translucent operating knob coaxial with, and removably connected to, one end of the rotor means for corotation therewith, and a light source removably mounted within said coaxial central passage for illuminating said knob, the improvement comprising:
- a pair of translucent chips mounted on the bottom side on each half of the knob adjacent said light source, each of said chips having a different color to indicate a particular selected operating position of the selector switch; and
a means for isolating light removably mounted and stationarily received within the coaxial central passage and disposed between said knob and said light source, said light isolating means having an aperture which permits light to pass through only the colored chip directly over the stationary aperture as the operating knob and the rotor means are selectively turned to the selected operating positions of the selector switch thereby sequentially changing the relative position of each chip with respect to said aperture. - View Dependent Claims (7, 8, 9)
- a pair of translucent chips mounted on the bottom side on each half of the knob adjacent said light source, each of said chips having a different color to indicate a particular selected operating position of the selector switch; and
