In some embodiments the control switch extends through an aperture in the a housing of the lighting fixture and the one or more devices are inserted into the aperture and embrace the control switch in one of the control switch's operational positions. In some embodiments the configuration of the apertures and the devices permits the devices to be inserted into the apertures in a single orientation.
