Abstract: Disclosed herein is a support device for supporting an article on a structure, the support device comprising an elongate body having a support head portion located at one end thereof, the support head portion including a head and a shoulder flange, the head and shoulder flange being separated by a neck, the head and/or neck being arranged to engage the article, the shoulder flange having a surface for engaging a corresponding surface of the structure, the elongate body further comprising an elongate shank portion for anchoring the support device at a target site on the structure.

Abstract: A device for supporting an article on a structure. The support device includes an elongate body with a head at one end, a neck, a shoulder flange, and an elongate threaded shank with threads extending therefrom. The head and/or neck may be arranged to engage the article, and the shoulder flange has a surface for engaging a corresponding surface of the structure. The elongate shank portion anchors the support device at a target site on the structure and tapers from a greatest diameter proximate to the shoulder flange to a pointed end. The initial taper is at a lesser angle to the longitudinal axis of the elongate body to a point where the angle increases, before which the threads may terminate.

Abstract: A pushbutton switch assembly to which an AC supply current or a DC supply current can be provided. The pushbutton switch assembly can include a pushbutton and a light-emitting diode that illuminates the pushbutton. The pushbutton switch assembly can also include a rectifier circuit that converts the AC supply current to a DC drive current and provides the DC drive current to the light-emitting diode. In some embodiments, the rectifier circuit can provide a DC drive current to the light-emitting diode regardless of a polarity of the DC supply current.
