Description

Static switch for wiring

Technical field

The present invention relates to a kind of detection and contact the static switch for wiring of the variation of the electrostatic capacitance that causes with the switching load circuit because of human body.

Background technology

The switch of using as house service used the mechanical switch that is provided with switch handle in the front of switch-box more in the past.But there is following problem in mechanical switch: because of the wearing and tearing of movable part, the stained longevity that causes, occupy bigger space etc. because of giving prominence to from wall.Therefore, proposed to utilize the static switching that contacts the variation of the electrostatic capacitance that causes because of finger tip.

Static switching shown in Figure 8 51 is for example disclosed in patent documentation 1.This static switching 51 is provided with guidance panel 53 in the inboard of trim 52, and is bonded with switch substrate 54 and insulated substrate 55 at the back side of guidance panel 53.Bury detecting electrode 56 in switch substrate 54 underground, the variation of the electrostatic capacitance when the detection finger tip touches guidance panel 53 comes the switching load circuit.

Patent documentation 1:JP spy opens flat 11-136116 communique

Yet according to existing static switching 51, guidance panel 53 is bonding with switch substrate 54, therefore the label that is used to guide the load place can't be installed.Therefore, under the situation of static switching that is a plurality of load equipments of operation, there is following problem: need be according to making the attached mark of making of switch markers, indicating and discern load equipment, the demonstration that can't freely change these by the end user.

Summary of the invention

Thereby the object of the present invention is to provide a kind of label that is used to guide the load place to be set to replaceablely can improve end user's the convenience and the static switch for wiring of operability.

Embodiment

Following with reference to description of drawings an embodiment of the invention.As shown in Figure 1, the static switching 1 of present embodiment comprises switch-box 2 that is installed on the indoor wall W (with reference to Fig. 4, Fig. 5) and the trim 3 that covers the front of switch-box 2.The peristome 4 of trim 3 is covered from the inboard by guidance panel 5, disposes guiding label 6 in the rear side of guidance panel 5.Guidance panel 5 is formed by transparent material, can have an X-rayed a plurality of display parts 7 on the guiding label 6 from the peristome 4 of trim 3 through guidance panel 5.

As Fig. 2, shown in Figure 3, switch-box 2 comprises the outer frame 10 that is built in the basket portion 9 in the wall W and is exposed to wall W.On two internal faces in opposite directions of basket portion 9, lug boss 11 is set, utilizes the screw 13 of the through hole 12 of inserting logical lug boss 11 that switch-box 2 is installed on the building materials of wall W inside.Accommodate circuit substrate 14 in the inboard of basket portion 9, as shown in Figure 4, this circuit substrate 14 is assembled in the switch-box 2 by the pushing pawl 16 that is arranged on the internal face different with lug boss 11 under the state that is supported by the support portion 15 on the both sides that are positioned at lug boss 11.

As Fig. 2, shown in Figure 5, keep with coincidence status configuration operation panel 5, guiding label 6 and switch substrate 18 and by trim 3 in the inboard of outer frame 10.On the two opposite edges of outer frame 10, respectively form two connecting holes 19, outstanding four snap-latch pieces 20 that are provided with respect to connecting hole 19 mounting or dismounting on the inner face of trim 3.On switch substrate 18, dispose a plurality of detecting electrodes 21 that when finger tip touches guidance panel 5, detect the variation of electrostatic capacitance.The display part 7 at expression load place is set and it is set to cover each detecting electrode 21 on the label 6 in guiding.In addition, detecting electrode 21 is connected with circuit substrate 14 by signal wiring (omitting diagram).

As Fig. 2, shown in Figure 3, on basket portion 9, be formed with supporting switch substrate 18 two limits par 23 and to the protuberance 24 of two other limit Fixed width of switch substrate 18.Switch substrate 18 with projection 25 consistent location of lug boss 11 on have installing hole 26, be fixed on the switch-box 2 by the chimeric of installing hole 26 and projection 25.On the position corresponding with the two ends of protuberance 24, form fastening hole 28 (with reference to Fig. 4) at the inner face of outer frame 10, go out to be provided with fastening pawl 29 in four cornicults of guidance panel 5 with respect to fastening hole 28 mounting or dismounting.

And, as Fig. 4, shown in Figure 5, overlapping guiding label 6 on the switch substrate 18, on guiding label 6 overlap operation panel 5 and fasten with outer frame 10, overlapping trim 3 and engage on guidance panel 5 with outer frame 10, thus under the state that will guide Label holder between guidance panel 5 and switch substrate 18, be installed in the switch-box 2.In addition, by taking off trim 3 and guidance panel 5, can take out guiding label 6 from switch-box 2, and be replaced by other guiding label 6.In addition, two limits in opposite directions of outer frame 10 are provided with the otch 30 (with reference to Fig. 2, Fig. 3) that is used for being peeled off by finger tip guiding label 6.

Therefore, according to the static switch for wiring 1 of above-mentioned formation, guiding label 6 is installed replaceably by the mounting or dismounting of trim 3 and guidance panel 5, so the end user can freely change the design of display part 7.For example, shown in Fig. 6 (a) and (b), provide the different a plurality of guiding labels 6 of design of display part 7 together, thereby the end user can select the guiding label 6 of the design liked and be installed in the switch-box 2 with the switch product.In addition, also can disconnect guiding label 6 with shear line 31 half as shown in Figure 7 on the printing sheets 32 that wires up with the switch product, the end user can use printer freely to design display part at the assigned address of guiding label 6.

Particularly, static switch for wiring 1 according to present embodiment, interior side superimposed at the outer frame 10 that is exposed to wall W disposes guidance panel 5, guiding label 6 and switch substrate 18, therefore when changing guiding label 6, under the state that switch-box 2 is installed, take off trim 3 and guidance panel 5 simply, just can easily change guiding label 6.At this moment, trim 3 is installed and removed with respect to outer frame 10 by snap-latch piece 20, guidance panel 5 is installed and removed with respect to outer frame 10 by fastening pawl 29, therefore have the following advantages: can not use screw and change guiding label 6, and can utilize snap-latch piece 20 and fasten the elasticity of pawl 29 and will guide label 6 to remain on the switch-box 2 strongly by singly touching mode.

The invention is not restricted to above-mentioned execution mode, for example also can be in guiding label 6 increase and decrease display part 7 quantity, in switch substrate 18 near the setting operation display lamp detecting electrode 21, on operation label 6, form loophole etc., in the scope that does not break away from purport of the present invention, can and constitute suitably change and implement the shape of each one.
