Description

Push switch

[technical field]

The utility model relates to a kind of push switch.

[background technology]

Along with the various electronic application Products Development and the release that are full of the consumption market, for the small-sized light current switch that cooperates this kind electronic product also is designed research and development in succession, push switch (being push-button switch) is wherein a kind of.

Known push switch sees also shown in Fig. 1,2, this push switch 1 includes one and can be assembled in and desire in conjunction with the pedestal on the object 11, this pedestal has a diapire 111, and one from the upwardly extending ring wall 112 of these diapire 111 peripheries, form opening room 113 up at

ring wall

112 and 111 of diapires, on ring wall 112, offer one uprightly and again, clip slot 114 in, install a top egative film 12 towards the clip slot 114 of room 113.This top egative film 12 has a frame 121 that is limited in the clip slot 114, and the outstanding supporting part 122 that in room 113, tilts, establish a location hook 13 in the top of frame 121 hook, the clip section 131 of this location hook 13 is subjected to supporting part 122 pushing tows and stretches in room 113, in order to reach to push purpose as the control conduction state, at least two conducting rods 14 that protrude from this diapire 111 of installing on the diapire 111 of this pedestal 11, assembling one pressing mechanism 15 in room 113, this pressing mechanism 15 is to shore at diapire 111 and by the spring 152 of 151 of wedges by wedge 151 bottoms assembling one one, be provided with a conducting element 153 that can touch conducting when moving down in bottom, in then installing a button of conveniently pushing 154 by wedge 151 tops with conducting rod 14 by wedge 151.

Known push switch 1 is positioned at an on-position or a de-energized in order to make this pressing mechanism 15, it is in forming a upright clip plate 16 by wedge 151 corresponding to the position of clip section 131, has a clamping face 161 towards clip section 131 on this clip plate 16, guide vane end stop 162 and on clamping face 161 below the direction outstanding of clip section 131 is positioned at is positioned at the bootstrap block 163 of top, constitute a slide rail 164 that can supply clip section 131 to move by this, this slide rail 164 has an energising anchor point 165 between 163 of guide vane end stop 162 and bootstrap blocks, and an outage anchor point 166 that is positioned at guide vane end stop 162 bottoms.

Known push switch 1 is under the state of outage, be subjected to supporting part 122 on the supporting piece 12 in push away, the clip section 131 of this location hook 13 is to be pushed to clamping face 161, and be positioned at outage anchor point 166 places of slide rail 164, this moment, spring 152 presented the state that supports, and 14 of conducting element 153 and conducting rods also do not contact.When desire control push switch 1 is "on" position, then be that the elastic force that overcomes spring 152 presses down this button 154, whole pressing mechanism 15 this moment (comprising clamping face 161) can move down, move down and under the highly constant state of location hook 13 at clamping face 161, this clip section 131 can be with respect to moving on the clamping face 161, and slide to location, pinnacled energising anchor point 165 places, position along its slide rail 164, so the conducting element 153 of pressing mechanism 15 promptly can contact conducting because of moving down with conducting strip 14, so that pressing mechanism 15 presents "on" position.

In like manner, when known push switch 1 desires to be transformed into off-position by "on" position, also press down this pressing mechanism 15, this moment is because the guiding of bootstrap block 163, this clip section 131 can be subjected to guiding leaves the energising anchor point 165 of location originally, gets back to original outage anchor point 166 places along slide rail 164 then, so under the situation that pressing mechanism 15 moves on respect to diapire 111, originally the conducting rod 14 and the conducting element 153 of contact can break away from butt, and form off-position.

Known push switch 1 is in order to reach to push the purpose as control device, yet, this push switch 1 must utilize a supporting piece 12 that is plugged on the pedestal 11, cause location hook 13 to continue to compress to the clamping face 161 of pressing mechanism 15, though above-mentioned structure can produce a desired effect, but must set up supporting piece 12 and number of assembling steps thereof in its assembling, and tiny location hook 13 is suspended on this supporting piece 12, the restriction of above-mentioned structure can cause the more and number of assembling steps of assembly element to wait disappearance more, and this push switch 1 causes energising or outage because of false touch easily, and therefore known push switch 1 still remains to be improved.
