Preferably, the middle foot son vertex in described bottom tub higher than foot in long limit in bottom tub and the summit of minor face foot, described springboard with middle foot for fulcrum does regulations and parameters motion, the two ends of springboard respectively with the apexes contact of long limit foot or minor face foot.
Preferably, described press component comprises button bar, is arranged at the copper bolt below button bar, the spring be sheathed on copper bolt, the bottom of described spacer is projecting to base direction a projection, and the top of described slide block is chevron, and described projection changes in ridge.
Preferably, the bottom pressing copper bolt described in button bar passes spacer bottom and abuts with slide block.
Preferably, described base is added an iron-clad, and described iron-clad and base are outer fixed by snap.
Preferably, described projection is inverted triangle.
The utility model gives prominence to effect: Long travel key control switch in the past changes into horizontal by vertical by this device, by the stator supplemental support increased newly, improves the stability of switch entirety of knowing clearly.Simultaneously the inner chevron slide block that adopts matches with the projection bottom spacer, maintains springboard and wherein limit foot UNICOM all the time, constitutes circuit of the present utility model at a certain state Xia Chang UNICOM state of switch.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail embodiment of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of this device.
Embodiment
As shown in Figure 1, the utility model discloses a kind of single-pole double throw Long travel key control switch.Consistent with prior art, described switch comprises copperhead 1, be connected to the base 2 with a bottom tub below copperhead 1, press component is equipped with in described copperhead 1, the bottom of described base 2 is connected with terminal, one end of described terminal is arranged with in bottom tub, and it is extended with outside base that the other end passes base 2, and described terminal comprises middle foot 42 and is separately positioned on long limit foot 41, minor face foot 43 of middle foot 42 both sides.Be disposed with springboard 21, spring 22, slide block 23 in described bottom tub from bottom to top, the top of described springboard 21 is connected with the bottom of slide block 23 by the spring 22 at two ends.Described base 2 is arranged with iron-clad 3.Described iron-clad 3 is provided with the feeler strengthening switch steady status, this structure similarly to the prior art, does not repeat them here.
Unlike the prior art, described press component comprises spring 13 sheathed on the copper bolt 12 arranged below one end is arranged at copperhead 1 top, one end is arranged at copperhead 1 inside button bar 11, button bar 11, described copper bolt 12; In order to press component in copperhead 1, the bottom of described copperhead 1 can be arranged with a stator 14, simultaneously for ensureing that stator does not drop, the bottom of described copperhead 1 embeds a spacer 15.Described spacer 15 center offers aperture, and the bottom of spacer 15 is provided with a projection 16 to base direction.The width of described spacer 15 is suitable with described stator 14; Pressing button bar 11, the aperture that the bottom of described copper bolt 12 can pass spacer 15 extends outside spacer 15.
Middle foot 42 summits in described bottom tub are higher than the summit of long limit foot 41 in bottom tub with minor face foot 43, described springboard 21 with middle foot 42 for fulcrum does regulations and parameters motion, the two ends of springboard 21 respectively with the apexes contact of long limit foot 41 or minor face foot 43.
The upper end of described slide block 23 is one " mountain " shape, is respectively the first slide block top 25, slide block top 24, second, the 3rd slide block top 26.Form the first ridge between described first slide block top 24 and the second slide block top 25, between described second slide block top 25 and the 3rd slide block top 26, form the second ridge.Described protruding 16 abut with the ridge of slide block 23, and described projection is preferably inverted triangle.
The below lower operation principle of the present utility model of summary:
Because protruding 16 and the top of slide block are all sharp protrusion, so both are when initial condition, can not completely on the same axis, therefore protruding 16 must at the first or second ridge place, now springboard 21 is also in heeling condition, namely the bottom of springboard 21 and middle foot 42 and wherein arbitrary limit foot be in UNICOM's state.
When pressing button bar 11, copper bolt 12 moves in bottom tub, abut to the top of slide block 23, by slide block 23 to pressing down, now, protruding 16 separate with slide block 23, due to springboard 21 and slide block 23 initial time be in heeling condition, press when being subject to copper bolt 12, when unclamping, slide block 23 can carry out the inclination of other direction, now, the summit of protruding 16 can enter another ridge place along with the motion of slide block 23, first slide block top 16 can limit the projection 6 entering ridge, thus play spacing effect, make springboard 21 that middle foot 42 is carried out UNICOM with limit foot of another side.Switch of the present utility model can make a certain state be in long-time UNICOM contact condition, without the need to being pressed for a long time by outer bound pair handle.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection range of the present utility model.
