For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of manual pull station contact switch, it is characterized in that: comprise horizontally disposed quiet shell fragment and the spring plate that is positioned at quiet shell fragment upper outer, described quiet shell fragment comprises horizontally disposed spring one and is arranged on spring one outer end and coupled inserted sheet one, described spring one the inner is provided with coupled spring two, angle α between described spring two and the spring one is 125 °～135 °, the outside, described spring two lower ends and close spring plate position are provided with the contact, described spring one, inserted sheet one, spring two and contact are one-body molded; Described spring plate comprises the spring three that be arranged in parallel with spring two, described spring three inboards contact with the contact, described spring three lower ends are outwardly-bent camber hook at the incline direction place, described spring three upper ends are vertically installed with coupled inserted sheet two, described inserted sheet two upper horizontal are provided with coupled inserted sheet three, described inserted sheet three parallels with inserted sheet one, and described spring three, inserted sheet two and inserted sheet three are one-body molded.
Above-mentioned manual pull station contact switch is characterized in that: the angle α between described spring two and the spring one is 130 °.
Above-mentioned manual pull station contact switch is characterized in that: described spring one, spring two and spring three are the linear pattern spring.
The utility model compared with prior art has the following advantages:
1, simple in structure, reasonable in design, this contact switch comprises quiet shell fragment and is positioned at the spring plate of quiet shell fragment upper outer, and is provided with the contact outside the quiet shell fragment lower end and near the spring plate position.
2, assembling is convenient and fast connection, and this contact switch is realized and being connected of printed circuit board (PCB) by being welded on contact pin on the printed circuit board (PCB).
3, can effectively improve the processing performance of manual pull station in batch production process, make its inner space lay and rationalize, and contact switch is fit to produce in batches.
4, volume is less, the size that this contact switch is regulated whole manual pull station by the height of adjusting quiet shell fragment and spring plate, and therefore not only volume is little for the contact switch of being produced, and good looking appearance.
5, use cost is low, and the cost of manufacture of this contact switch has only 1/5th of sensitive switch.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
A kind of manual pull station contact switch as illustrated in fig. 1 and 2, comprise horizontally disposed quiet shell fragment 1 and the spring plate 2 that is positioned at quiet shell fragment 1 upper outer, described quiet shell fragment 1 comprises horizontally disposed spring 1 and is arranged on spring one 3 outer ends and coupled inserted sheet 1, described spring one 3 the inners are provided with coupled spring 25, angle α between described spring 25 and the spring 1 is 125 °～135 °, the outside, described spring 25 lower ends and close spring plate 2 positions are provided with contact 7, described spring 1, inserted sheet 1, spring 25 and contact 7 are one-body molded; Described spring plate 2 comprises the spring 38 that be arranged in parallel with spring 25, described spring 38 inboards contact with contact 7, described spring 38 lower ends are outwardly-bent camber hook 9 at the incline direction place, described spring 38 upper ends are vertically installed with coupled inserted sheet 2 10, described inserted sheet 2 10 upper horizontal are provided with coupled inserted sheet 36, described inserted sheet 36 parallels with inserted sheet 1, and described spring 38, inserted sheet 2 10 and inserted sheet 36 are one-body molded.
