Embodiment Construction

[0046] refer to Figure 1 to Figure 3 , which illustrates a typical embodiment of an "industrial" electronic switching device.

[0047] The switchgear 1 comprises a substantially box-shaped base 2 (in Figure 6 described separately in ), which provides the space for the switchgear to operate, the base has a front face 4 and an opposite rear face 6, so that the base 2 can be fastened to a support surface.

[0048] Rotatably located on the front face 4 of the base 2 is a rotary switch (or knob) 8; axis, which is normally aligned with the end face 10 of the disk.

[0049] A pair of symmetrical approximately semicircular recesses are molded onto the end face 10 of the rotary switch 8, whereby the switch end face 10 consists of an annular peripheral edge 12 with an outwardly projecting lip, and a ring extending from one edge to the other. One end is defined by a rib 16 . The rib 16 is a portion that the user can grasp (usually between the thumb and forefinger) to turn the rotar...

Abstract

This invention relates to an electrical switch assembly (1) comprising a rotary switch (or knob) (8) rotatably nested within a base (2), where there is an aperture through both a portion of each of the rotary switch (8) and the base (2), where these apertures (20 and 30) may be aligned when the rotary switch (8) is set in a selected position (usually the "Off position) so that a shank of a padlock may be passed through these aligned apertures (20 and 30) and locked closed so as to prevent rotation of the rotary switch (8) relative to the base (2). At least the aperture (20) through the base (2) portion is positioned and / or directed so as to reduce moisture and / or particulate incursion.

Description

technical field [0001] The present invention relates to improvements in electronic switching devices. [0002] For the purposes of explanation, reference will be made to "industrial" electronic switching gear, although the invention is not limited to application to this type of switching gear, it may also be used in non-industrial or domestic electronic switching gear. [0003] priority document [0004] The priority claim for this patent application is derived from: [0005] Australian Provisional Patent Application AU 2008906561 entitled "Improvement in Electronic Switchgear", filed 22 December 2008. [0006] The entire contents of this application are incorporated herein by reference. Background technique [0007] Industrial electronic switchgear is suitable for use in environments exposed to dust, powder and moisture, such as outdoor environments, and harsh indoor environments, such as warehouses and factories. [0008] One type of industrial electronic switchgear co...
