Description

A Switch Arrangement The present invention relates to a switch arrangement and to an electrical connection arrangement; in particular, certain embodiments relate to switched and unswitched fused connection units.

Certain switch arrangements, referred to hereinafter as "switched fused connection units", are intended for use in powering electrical equipment that does not have a fused plug, and/or for powering high powered electrical equipment with heavy continuous loads. In addition to a switch for making and breaking the circuit, switched fused connection units incorporate a fuse; an example of a switched fused connection unit is a switched fused spur, e.g. a 13 amp switched fused spur. Switched fused connection units are often used with appliances that are mounted in a permanent position; for example in domestic use, with extractor fans in the kitchen or bathroom.

Existing switched fused connection units typically position the fuse under a dedicated screw-fitted fuse cover or within a pull-out fuse holder located adjacent the switch on the fascia of the switched fused connection unit.

A problem associated with known switched fused connection units is that a child may seek to investigate the fuse cover or fuse holder and the associated fuse, particularly given the unusual appearance (relative to e.g. a light switch) of the switched fused connection unit, with the associated risks of an electrical shock being delivered to the child and/or of an important circuit being inadvertently broken by removal of the fuse.

Similar problems are encountered with unswitched fused connection units, which are similar to switched fused connection units but omit a switch.

Additionally, the size of the switch of a switched fused connection unit is limited, to permit its location adjacent the fuse cover or holder on the switched fused connection unit fascia. This may make the switch inconvenient to operate for certain users e.g. the elderly or those with disabilities.

It is, therefore, an object of the present invention to seek to alleviate the above identified problems.

SUMMARY OF THE INVENTION

By using the switch to obscure the fuse receiving portion, the likelihood of a child being motivated by curiosity to investigate the switch arrangement is reduced or avoided altogether, particularly in embodiments where the resulting switch arrangement resembles a conventional switch e.g. light switch. It has been found that the aesthetics of the switch arrangement of the present invention are much improved so that the switch arrangement can be designed to "blend in" with the other switches and sockets in a room. By creating a uniform aesthetic the switch arrangement is safer because it is less likely to stand out and attract attention from a child.

Within this specification embodiments have been described in a way which enables a clear and concise specification to be written, but it is intended and will be appreciated that embodiments may be variously combined or separated without parting from the invention. For example, it will be appreciated that all preferred features described herein are applicable to all aspects of the invention described herein and vice versa.

In order that the present invention may be more readily understood, embodiments thereof will now be described with reference to the accompanying figures, of which: FIGURE 1 shows a switch arrangement according to a first embodiment of the present invention in an unassembled condition; FIGURES 2 and 3 show the switch arrangement of Figure 1 in an assembled condition and in "off" and "on" positions, respectively; FIGURE 4 shows a switch arrangement according to a variant of the first embodiment of the present invention; FIGURE 5 shows a switch arrangement according to a second embodiment of the present invention; FIGURE 6 shows part of a switch arrangement according to a third embodiment of the present invention in an unassembled condition; FIGURE 7 shows the switch arrangement of Figure 6 in a fully-assembled condition; FIGURE 8 shows an electrical connection arrangement according to a fourth embodiment of the present invention; FIGURE 9 shows the arrangement of Figure 8; FIGURE 10 shows part of the arrangement of Figure 8 in an unassembled condition; FIGURE 11 shows a variant of the fourth embodiment; and FIGURE 12 shows a fifth embodiment of the present invention.

Figure 1 shows a switch arrangement 1, according to a first embodiment of the present invention, in an unassembled condition. The switch arrangement 1 is provided with a switch formed by a toggle switch 3, which is pivotally mounted to a backing plate 5, and a switch button 7 which clips and unclips to the toggle switch 3, and to which a user applies force to move the switch between "on" and "off' positions. The switch arrangement 1 of the present embodiment comprises a single pole switch arrangement, i.e. it is used to control the flow of current through a single circuit.

In Figure 1, the switch button 7 has been unclipped from the toggle switch element 3 and removed from the backing plate 5 in the direction shown by the arrow A, to reveal a slide-out fuse holder or carriage 9 underneath. The fuse holder or carriage 9 was previously concealed by the switch button 7. In use, the fuse holder 9 contains a fuse 10 (shown in dotted lines in Figure 1). The fuse holder 9 is marked "FUSE" for ready identification and is provided with a recess 13 to facilitate its extraction from the backing plate 5.

A frame 15 is mounted to the backing plate 5 and surrounds the switch button 7 when the switch button 7 is mounted to the toggle switch element 3. The frame 15 may be used to conceal any screws or similar fixture means used to fix the switch arrangement to a surface such as a wall. A coloured light emitting diode (LED) 17 is further provided in the backing plate 5 and a clear lens 19, through which light from the LED 17 is permitted to pass, is provided in the switch button 7 at a position corresponding to the location of the LED 17.

Figures 2 and 3 show the assembled switch arrangement 1 with the switch button 7 attached, and with the switch arrangement 1 in "oft' and "on" positions, respectively.

Referring to Figure 3 in the "on" position, an electrical connection is made between the fuse (not shown) and a terminal of the switch arrangement 1; when the switch arrangement 1 is installed in an electric circuit, current is thus permitted to flow through the circuit via the fuse and the electrical connection made to it by the switch. Further, the LED 17 illuminates when the switch is in the "on" position with current flowing through the circuit via the switch arrangement 1. Referring to Figure 2, in the "off" position, the electrical connection to the fuse is broken such that current is prevented from flowing through the circuit via the fuse, and the LED 17 is not illuminated.

Further, when the switch is in the "off" position as shown in Figure 2, a recess 21 formed in an edge of the switch button 7 is revealed. This recess 21 may be engaged, e.g. using a dedicated tool shaped to co-operate with the recess (and which, according to an embodiment, is provided as part of a kit together with the switch arrangement 1) or e.g. by any suitable implement such as a flat head screwdriver, to gain a purchase on, i.e. to grip, the switch button 7 and hence facilitate its removal from the toggle switch 3, to enable a user to access the fuse holder 9. The fuse holder 9 may then simply be slid out to access the fuse. When the switch is moved to the "on" position, this recess 21 is hidden by the frame 15 and hence is rendered inaccessible.

As will be appreciated, therefore, the recess 21 (which facilitates removal of the switch button 7) may only be accessed when the switch arrangement 1 is made safe by putting it into the "off" position.

Further, it will be appreciated that in the present embodiment the fuse holder 9 (and hence the fuse 10 itself) is hidden from view by the switch button 7.

In a variant, the switch arrangement 1 according to the first embodiment of the present invention is provided with a flex outlet aperture 22 in the switch button 7, as shown in Fig. 4, which allows for an electrical flex to pass therethrough to a connected device e.g. a water immersion heater (not shown).

Figure 5 shows a switch arrangement 1 according to a second embodiment of the present invention. This embodiment differs from the first embodiment in that it is provided as a module 23 without a surrounding frame and wherein the backing plate occupies only the footprint of the switch button 7. A plurality of flange portions 25 protrude from the backing plate to facilitate fixture of the module 23 to a wall plate. The present embodiment is otherwise the same as the first embodiment. In a variant of the second embodiment, a flex outlet aperture may be provided, for example in the switch button 7.

Figures 6 and 7 show a switch arrangement 1 according to a third embodiment of the present invention. The present embodiment differs from the first embodiment described above in that it is a double-pole switch, whereby the flow of current through two separate circuits is controlled by the single switch arrangement 1. In the present embodiment, two separate toggle switches 3 are pivotally mounted to the backing plate 5, each to control the flow of current to a respective circuit. The switch button 7 is removably mounted to both of these toggle switch elements 3, and by applying a force to the single switch button 7 a user simultaneously provides or interrupts a flow of current through the two circuits. In further embodiments, the switch button 7 is removably mounted to additional toggle switch elements to provide, for example, a triple pole switch arrangement 1, for simultaneously providing or interrupting a flow of current through a further number of circuits e. g. three circuits. In a variant of the third embodiment, a flex outlet aperture may be provided, for example in the switch button 7.

Figure 8 shows an electrical connection arrangement 27 according to a fourth embodiment of the present invention.

Unlike the preceding embodiments, the present embodiment is unswitched. A cover 29 is located over a fuse receiving portion 31 (see Fig. 10) in which a fuse (not shown) is located. The fuse receiving portion 31 is provided with electrical terminals (not shown) for making electrical connections to the fuse. The cover 29 resembles a switch button, but does not perform any switching function and in particular is not operable to make or break any electrical connection to the fuse. In the present embodiment, the cover 29 is entirely static i.e. does not move upon pressure being applied to it, but in a further variant of the present embodiment the cover 29 may move like an actual switch button, but without making or breaking any electrical connection to the fuse.

The electrical connection arrangement 27 is further provided with a light source 33 e.g. a neon light or Light Emitting Diode (LED) which is illuminated when electrical current flows through the fuse. The cover 29 is provided with a translucent window portion 35 permitting light from the light source 33 to pass.

The cover 29 is removably mounted to a backing plate 37, for example by a "snap-fit" type arrangement; Figure 10 shows the electrical connection arrangement 27 with the cover 29 removed. The cover 29 is further provided with a recess 39 for removing the cover 29 from the backing plate 37. In variants where the cover 29 moves like an actual switch button, the recess 39 may be concealed when the cover is in a first position and revealed when the cover is in a second position. A frame 41 surrounds the cover 29 and may be used to conceal any screws or other fixing means which may be used to fix the electrical connection arrangement 27 to a surface such as a wall.

An electrical flex outlet 43 in electrical communication with one of the terminals of the fuse receiving portion 31 is provided in the backing plate 37, and an electrical flex outlet aperture 45 is provided in the cover in a corresponding location, to permit electrical flex to pass through the cover 29.

A variant of the fourth embodiment is shown in Figure 11, in which the electrical flex outlet and electrical flex outlet aperture are omitted.

A fifth embodiment of the present invention is shown in Figure 12. This embodiment differs from the fourth embodiment in that it is provided as a module 47 without a surrounding frame and wherein the backing plate occupies only the footprint of the cover 29. A plurality of flange portions 49 protrude from the backing plate to facilitate fixture of the module 47 to a wall plate. In a further variant, the electrical flex outlet and electrical flex outlet aperture are omitted. The fifth embodiment is otherwise the same as the fourth embodiment described above.

It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention as defined by the claims and without diminishing its attendant advantages. It is therefore intended that such changes and modifications are covered by the appended claims.

A non-exhaustive and merely exemplary selection of such further changes and modifications falling within the scope of the present invention is set out in the following.

Whilst the above examples relate to pivotable "rocker"-type switches, embodiments of the present invention may be applied to further switch types e.g. toggle switches, or switches with rotary knobs or dials. Further, embodiments of switch arrangements according to the present invention may also extend beyond mechanical switches, e.g. to touch-sensitive switches (such as, for example, capacitance-based touch switches, resistance-based touch switches of piezo-based touch switches) where a user need only apply a gentle contact force to actuate the switch. In embodiments, the switch may be controlled by a user inputting one or more pre-defined gestures to the switch arrangement via the touch-sensitive switch. In still further embodiments, non-mechanical switches may for example further include wirelessly controlled switches. Wireless control protocols suitable for controlling such wirelessly controlled switches may include, without limitation, zigbee, z-wave, Bluetooth or Wi-Fi. In embodiments employing non-mechanical switches, the need for mechanical switch control means such as one or more switch toggles 3 may be avoided.

According to embodiments of switch arrangements according to the present invention, the switch may be controlled e.g. by an application ("app") running on an electronic device such as a mobile telephone, tablet, laptop or desktop computer.

Although the above-described embodiments utilise an LED as a light source for indicating if current is flowing, other light sources may be used e.g. neon lights; alternatively, no light source need be included.

In the above-described first embodiment, the recess 21 is revealed when the switch button is in the "off" position. In an alternative embodiment, an engagement portion for facilitating removal of the switch button is instead only revealed upon removal of the frame surrounding the switch button.

In the above-described embodiments, the fuse is mounted in a slide-out fuse holder, with each of the fuse and fuse holder being located under the switch button. In an alternative embodiment, the fuse may instead be located within a recess within the backing plate, and covered by a fuse cover plate, with both the fuse and fuse cover plate being located under the switch button. In some embodiments, the fuse cover plate is held in place by a screw. In still other embodiments, the fuse cover plate may simply be held in place under tension e.g. by clipping into place, or the fuse cover plate may be omitted altogether; such further embodiments may be particularly convenient for certain users e.g. the elderly or disabled, as no screw need be removed to access the fuse. In yet further embodiments, the fuse may instead be mounted in a removable cartridge.

The above described embodiments employ a frame 15, which may conveniently be used to conceal any screws or other fixture means which may be used to fix the switch arrangement to a surface such as a wall. In other embodiments, the frame may be omitted and the screws may remain visible as in standard switches.
