Abstract

An electrical wall panel switch comprising: a panel for securing to a wall; a switch assembly connected to the panel, the switch assembly including a pivotal trigger for causing a switching action in the switch assembly as a result of the pivotal movement. The flip-flop includes a pair of interfacing surfaces. A switch tap lever is pivotally mounted about the shelf and has a pair of actuators, each actuator being aligned with one of the abutment surfaces and pressing against the abutment surface to cause pivotal opening and closing movement of the trigger.

Description

Electric wallboard switch

Technical field

The present invention relates to the such switch for for example electric mains voltage lamp of opening and closing and ceiling fan.More particularly, but not exclusively, the present invention relates to have the wallboard switch of detachable and reconfigurable switch module.

Background technology

Known lighting switch for example comprises the lattice plate being screwed on wall.Lattice plate has the preassembled switch module snapping fit onto from behind in respective socket.Depend on the position of the socket of use, the lattice plate of standard can be provided with one, two or more switches or other device (such as dimmer switch).

The problem of known structure is, because of the object of for a change and/or again connecting wires, in order to touch switch module, under the wall dismounting that lattice plate must be installed to from it to touch switch module below from lattice plate.

Another problem of known structure is, come out and very approach and electrically contact breaker points with the switching toggle bar with finger actuated, although therefore accidental arc discharge-itself is not dangerous-may around poke rod, present the spark/flash of light that may make user alarmed.

Summary of the invention

The object of the invention is to overcome or improve in fact at least one above-mentioned shortcoming and/or a kind of improved electric wallboard switch is more generally provided.

Disclose a kind of electric wallboard switch at this, comprising:

For being fixed to the lattice plate on wall;

Be connected to the switch module on lattice plate, switch module comprises the pivot trigger that causes switch motion due to pivot motion in switch module, and trigger comprises a pair of abutted surface; And

The switching toggle bar of pivotally installing about lattice plate, switching toggle bar comprises a pair of actuator, abutted surface is aimed at and optionally pushed to each actuator to cause the described pivot motion of trigger with in described abutted surface one in fact.

Preferably, lattice plate is included in the through hole that wherein holds switch module.

Preferably, lattice plate comprises the notch around through hole, also further comprises that the base plate and the switching toggle bar that are contained in notch are pivotally installed to base plate.

Preferably, electric wallboard switch further comprises and is connected to lattice plate to hide the panel of base plate, and panel frame is lived switching toggle bar.

Preferably, wherein lattice plate is included in through hole multiple slits around, and wherein switch module comprises multiple protuberances that are contained in slit.

Brief description of the drawings

By example, preferred form of the present invention is described now with reference to accompanying drawing, wherein:

Fig. 1 is the schematic part exploded perspective view of electric wallboard switch;

Fig. 2 is the schematic cross sectional views of the electric wallboard switch that formed by the each assembling parts in Fig. 1;

Fig. 3 is the schematic perspective view of switch trigger; And

Fig. 4 is the schematic perspective view of switching toggle bar.

Embodiment

Fig. 1 in accompanying drawing schematically illustrates the various parts of composition two switch electric wallboard switch.

The lattice plate 10 of moulding of plastics materials comprises multiple screw holes 15, and lattice plate 10 is fixed on wall by screw hole 15.For stud wall, will the mounting panel with the screw hole of aiming at screw hole 15 be set after plasterboard.For brick wall or concrete walls, interior wall switch enclosure will have the screw hole of aiming at screw hole 15.Lattice plate 10 comprises by the circumjacent through hole 16 of notch 28.There are multiple slits 29 at the inner rim of through hole 16.

Switch module 11 each has the trigger 17 of pivotally installing at pivot 18 places.In Fig. 3, demonstrate preferably in trigger 17, it has shown the abutted surface 22 in pivot 18 sides.Multiple protuberances 30 extend out and are assembled in the respective slots 29 of lattice plate so that switch module 11 is accurately located from each switch module 11.When being assembled to behind appropriate location, the main body of each switch module extends through through hole 16.Should be appreciated that switch module 11 can be connected to lattice plate 10, simultaneously lattice plate appropriate location on the wall., need to not take off for coupling assembling 11 lattice plate 10.Electric wire is pulled through through hole 16 simply to can be fixed on switch module 11, and then assembly is pushed the appropriate location on lattice plate simply.

Base plate 12 is mounted in notch 28 before the switch module in original position.Base plate 12 comprises the multiple holes 20 before the abutted surface 22 that is directly positioned in switch module trigger 17.Although only shown two switch modules in figure, three pairs of holes 20 that are applicable to maximum three switch modules 11 are shown.

Base plate 12 has multiple pivotal mounting seats 19 that each switching toggle bar 14 is pivotally mounted thereon.Each switching toggle bar is very large and comprise indicator light 31 compared with traditional switch poke rod.

Panel 13 is assemblied on lattice plate 10 own to hide base plate 12, switch module 11 and lattice plate 10.Panel 13 comprises that frame lives the macropore 21 of switching toggle bar 14.

One in switching toggle bar 14 is presented in Fig. 4.It comprises handle pivot (pivot lug) 24, and handle pivot 24 engages to poke rod is pivotally installed on base plate 12 with respective pivot mount pad 19.In handle pivot 24 sides and what extend back from poke rod 14 is a pair of actuator 23.In structure after the assembling of wallboard switch as shown in Figure 2, each actuator 23 extends through a hole 20 separately to be supported on the abutted surface of switch trigger 17.Show that Fig. 2 that the assembling of wallboard switch is constructed afterwards has also shown the typical internal structure of a switch module 11.In addition, switch module comprises electric contact 25, and pivot conduction breaker lever 26 can join electric contact 25 to so that with conductive pillar 32 closed circuits.Be provided with spring below at trigger 17 and load piston 27, it is bearing on breaker lever 26.In illustrated closing (OFF) position, in the time pressing poke rod in bottom and rotate around handle pivot 24, spring loads piston 27 remains against on insulation brake 31 breaker lever 26, lower actuator 23 supports lower abutted surface 22 and crosses so that piston 27 moves upward the center being limited by pillar 32, thereby the supporting contact 25, upper end of breaker lever 26 is with closed circuit.

Should be appreciated that apparent change for a person skilled in the art and replace and should not be regarded as having exceeded scope of the present invention.Especially, although illustrated embodiment has shown a pair of poke rod 14 and pair of switches assembly 11, the present invention is applicable to single switch, biswitch, three switches or four switches too.
