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 be used for for example such switch of electric mains voltage lamp and ceiling fan of opening and closing.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 with screw and is fixed to lattice plate on the wall.The lattice plate has the preassembled switch module that snaps fit onto from behind in the respective socket.The position of depending on the socket of use, the lattice plate of standard can be equipped with one, two or more switches or other device (such as dimmer switch).

The problem of known structure is, because the purpose that changes and/or connect wires, in order to touch switch module, the lattice plate must touch switch module with the back from the lattice plate down from its wall of being installed to dismounting.

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

Summary of the invention

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

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

Be used for fixing the lattice plate on the wall;

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

About the switch poke rod that the lattice plate is pivotally installed, the switch poke rod comprises a pair of actuator, each actuator in fact with described abutted surface in one aim at and optionally push abutted surface to cause the described pivoting action of trigger.

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

Preferably, the lattice plate comprises the notch around through hole, comprises further that also the base plate and the switch poke rod that are contained in the notch pivotally are installed to base plate.

Preferably, electric wallboard switch comprises further and is connected to the lattice plate to hide the panel of base plate that the panel frame is lived the switch poke rod.

Preferably, wherein the lattice plate is included in through hole a plurality of slits on every side, and wherein switch module comprises a plurality of protuberances that are contained in the slit.

Description of 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 each component-assembled among Fig. 1;

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

Fig. 4 is the schematic perspective view of switch poke rod.

Embodiment

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

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

Each of switch module 11 all has the trigger of pivotally installing at pivot 18 places 17.Demonstrate in the trigger 17 in Fig. 3 preferably, it has shown the abutted surface 22 in pivot 18 sides.A plurality of 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.After being assembled to the appropriate location, the Subject Extension of each switch module is passed 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.That is, need not take off lattice plate 10 for coupling assembling 11.Electric wire is pulled through through hole 16 simply so that can be fixed on the switch module 11, and assembly is pushed the appropriate location on the lattice plate simply then.

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

Base plate 12 has a plurality of pivotal mounting seats 19 that each switch poke rod 14 pivotally is mounted thereon.Each switch poke rod is compared very big and is comprised indicator light 31 with the conventional switch poke rod.

Panel 13 is assemblied on the 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 switch poke rod 14.

One in the switch poke rod 14 is presented among Fig. 4.It comprises handle pivot (pivot lug) 24, and handle pivot 24 engages so that poke rod pivotally is installed on the base plate 12 with respective pivot mount pad 19.What extend back in handle pivot 24 sides and from poke rod 14 is a pair of actuator 23.In the structure after the assembling of as shown in Figure 2 wallboard switch, each actuator 23 extends through separately a hole 20 with on the abutted surface that is supported on switch trigger 17.Shown that the Fig. 2 that constructs after the assembling of wallboard switch 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-loaded piston 27 in trigger 17 back, it is bearing on the breaker lever 26.In illustrated closing (OFF) position, when pressing poke rod in the bottom around handle pivot 24 rotations, spring-loaded piston 27 remains against on the insulation brake 31 breaker lever 26, the lower lower abutted surface 22 of actuator 23 supportings is crossed the center that is limited by pillar 32 so that piston 27 moves upward, thereby supporting contact 25, the upper end of breaker lever 26 is with closed circuit.

Should be appreciated that conspicuous for a person skilled in the art change 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.
