Embodiment

Comprise the shell 2 of an insulation at the electric switchgear shown in Fig. 11, only local one and half shells of expressing this shell among the figure.In order to see enclosure, the second half shells of protection against electric shock closure 2 do not illustrate.On the housing face-plate 3 of shell 2, be provided with a switch lever 4 and be used for manual control switching device 1.At this, this housing face-plate 3 is confined state lower casing 2 sides in the face of the operator.Switch lever 4 comprises a cylindrical rotor 5, and it is around its cylinder axis or rotation 6 is rotatably supported in the shell 2 and its cylindrical leans internally on an opening in shell 7 of housing face-plate 3.As what seen among Fig. 2 by detailed expression switch lever 4 especially, switch lever 4 also comprises a handle 8 and a control arm 9.Handle 8 and control arm 9 is formed on the excircle of rotor 5 with an obtuse angle each other and radially outwards protrudes with respect to rotation 6 therefrom.Switch lever 4 is put into shell 2 the insides like this, and it is outstanding from shell 2 to make handle 8 pass opening in shell 7, and control arm 9 is arranged on shell 2 inside.

In order to realize a position of the switch indicating device 10, a housing window 11 is contained on the housing face-plate 3, import a sign 12 movably in this housing window back.A guide section 13 that is arranged on shell 2 inside is used as the guide of sign 12, and this guide section 13 has very little spacing apart from housing face-plate 3 and is arranged essentially parallel to this panel 3 and extends.Between housing face-plate 3 and guide section 13, form a banded guide channel 14 of sign 12.

In Fig. 3, be illustrated in detail in the sign 12 that only schematically shows among Fig. 1.It has a band like form and is made by a kind of flexible material, especially a kind of plastic film or elastic film.Described sign 12 vertical 15 is divided into two

indicator

16a and 16b along it, and they have for example different color marks.Sign 12 longitudinal end adjacent with indicator 16a is as stiff end 17 and be used for sign 12 is fixed on switch lever 4.Stiff end 17 has a fixed lobe 18 for this reason, and it can shape inserts corresponding with it holddown groove 19 the insides of switch lever 4 control arms 9 roots (and therefore on rotor 5 circumference) sealedly.This holddown groove 19 does not extend on the whole width of switch lever 4, but seals by stop wall 20 in the end.Fixed lobe 18 correspondingly has the end with respect to lateral edges 21 retractions, and it is used as the stop surface 22 when sign 12 is injected holddown groove 19.The size of design stop surface 22 and stop wall 20 makes that sign 12 and switch lever 4 are along the mutual centering of the direction of rotating shaft 6 when fixed lobe 18 is advanced holddown groove 19 the insides fully like this.

Shell 2 during taking-up switch lever 4 shown in Figure 4.Especially as can be seen form in the guide channel 14 between housing face-plate 3 and the guide section 13 in this view, it extends below housing window 11.On the extension of guide section 13, another shell section 23 has the thickness thinner than guide section 13.Shell section 23 extends out from guide section 13 with ground, housing face-plate angle at 45 approximately, so shell section 23 makes guide channel 14 enlarge towards rotation 6 funnel-forms ground.One is positioned on unshowned the second half shells of shell 2 with second shell section of 23 one-tenth symmetrically arranged same structures of mirror image of this shell section under assembling finishes state.

Fig. 5 and 6 expresses the working method of position of the switch indicating device 10 and the acting in conjunction of sign 12 and switch lever 4.Represent that at this Fig. 5 switching device 1 is in first position of the switch, be in the position that deviates from housing window 11 and control arm 9 directly leans on housing face-plate 3 on next-door neighbour's guide sections 13 ground at this position handle 8.This position of the switch of switch lever 4 is corresponding with an indicating positions of

sign

12, and 16a leans on housing window 11 in this indicator, position.Therefore the user can see the color mark of indicator 16a in housing window 11.

For master cock device 1 turns to terminal location shown in Figure 6 with handle 8 for about 60 ° from initial position deflection shown in Figure 5.Control arm 9 also rotates when switch lever 4 moves.Control arm 9 is as the drop-down sign 12 of planker simultaneously.Second indicating positions in the 4 second switch positions of the switch lever shown in Fig. 6 corresponding to sign 12,16b leans on housing window 11 in this indicator, position, so the user can see the color mark of indicator 16b from housing window 11.

Shell section 23 is flat in this wise on the one hand, so that it can not hinder the rotation of control arm 9.The gauge of shell section 23 is stuck in after the sign 12 it from the side on the other hand.Therefore realize sign 12 the cylindrical of rotor 5 and and the shell section 23 of the tangent substantially setting of rotor 5 between the enforced guiding motion.This enforced guiding motion especially has meaning when second switch position shown in Figure 6 turns back to first position of the switch shown in Figure 5, because can prevent that by shell section 23 elasticity sign 12 is shed to enclosure interior.

Switch lever 4 is parts of the switching device that does not all illustrate 1 operating mechanism.Under assembling finished state, control arm 9 acted on one or more switch contacts by a switch operating mechanism that does not illustrate, and these switch contacts disconnect or connection according to the position of the switch of switch lever 4.Therefore, the indicating positions of sign 12 is single corresponding with the position of the switch of switch contact clearly, and therefore corresponding with the operating state of switching device 1.
