The utility model provides a kind of microswitch with signaling transfer point comprising pedestal 1 is arranged on the pedestal 1 There are microswitch ontology 2, the driving that the microswitch ontology 2 has action reed 3 and is rotatablely connected with the action reed 3 Wheel 4, wherein be additionally provided with changeover mechanism on the pedestal 1；The changeover mechanism includes the shaft being arranged on the pedestal 1 5, the interconnecting piece 6 being rotatablely connected with the shaft 5, active shrapnel 7 and from spring plate 8；It is described from one end of spring plate 8 with it is described Interconnecting piece 6 connects, and the other end is contacted with the driving wheel 4；Described 7 one end of active shrapnel is connect with the interconnecting piece 6, the other end It extends to outside the pedestal 1；The active shrapnel 7 is used to push the interconnecting piece 6 to be rotated relative to the shaft 5, to drive It is described to squeeze the driving wheel 4 from spring plate 8.

By driving wheel 4 described in pressed by external force, make the driving wheel 4 that the action reed 3 be driven to move, thus by external force Be transmitted to the spring structure that the microswitch carries on the back internal portion, push travelling contact carry out the course of work of switch motion with it is existing Microswitch structure in technology is identical, is no longer illustrated to the structural principle in the utility model.

Preferred embodiment, the microswitch with signaling transfer point carry out first element 100 and second element 200 The goodness of fit detects.The pedestal 1 is installed in the first element 100, and the active shrapnel 7 is made to extend to the bottom One end outside seat 1 equally extends to outside the first element 100, in order to push the second element 200 close to described first When element 100, the second element 200 can be contacted with the active shrapnel 7, and to 7 conductance of active shrapnel.It is described It is contacted always with the driving wheel 4 from spring plate 8；When the second element 200 is from 7 one side of active shrapnel to described first Element 100 is close and when being contacted with the active shrapnel 7, the second element 200 can squeeze the active shrapnel 7 far from described One end of interconnecting piece 6, by lever principle, the active shrapnel 7 pushes the interconnecting piece 6 to be rotated around the shaft 5, to drive It is described to be moved from the one end of spring plate 8 far from the interconnecting piece 6 towards the microswitch ontology 2, push the driving wheel 4 with It drives the action reed 3 to press, realizes the closure of the microswitch ontology 2.The changeover mechanism is the microswitch Ontology 2 increases signaling transfer point, to expand the detection range of the microswitch ontology 2.

The interconnecting piece 6 is U-shaped interconnecting piece, and the opening of the U-shaped interconnecting piece deviates from the driving wheel towards the pedestal 1 4 one end, the U-shaped interconnecting piece include the first rotatable lamella 61 being set in the shaft 5 and the second rotatable lamella 62 and by institute The connecting plate 63 of the first rotatable lamella 61 and second rotatable lamella 62 connection is stated, second rotatable lamella 62 is rotated with described first Piece 61 is symmetrical above and below.

It the active shrapnel 7 and described is connect from spring plate 8 with the connecting plate 63；The shaft 5 and the pedestal 1 It is fixedly connected, first rotatable lamella 61, second rotatable lamella 62 are rotatablely connected with the shaft 5.Due to the driving Wheel 4 has certain width, described to realize accurate conduction of the changeover mechanism to 200 exerted forces of the second element First rotatable lamella 61 and second rotatable lamella 62 in the form of sheets, have certain height.Preferably, the connecting plate 63, institute It states active shrapnel 7 and the height from spring plate 8 is equal.

It is described to be parallel to the action reed 3 from spring plate 8 when initial, it is described to be connect from spring plate 8 and the driving wheel 4 It touches, the angle between spring plate 8 and the connecting plate 63 is 90 °, between the active shrapnel 7 and the connecting plate 63 Angle be obtuse angle, preferably, the angle between the active shrapnel 7 and the connecting plate 63 is 125 °.The active shrapnel 7 Connect with the connecting plate 63 one end and it is described connect from spring plate 8 with the connecting plate 63 one end by the connecting plate 63 every Leave, and the active shrapnel 7 and it is described can be with stress deformation from spring plate 8 so that the first element 100 and described the Even if two element 200 be closed after have gap or have shake situation it is described from spring plate 8 if resiliently press the driving wheel 4, make The driving wheel 4 is constantly in stress tightly by state, so that test result is unaffected.

Since the active shrapnel 7 can generate elastic deformation under external force, for avoid the second element 200 by It is larger to push the dynamic shock active shrapnel 7, it causes 7 deflection of active shrapnel excessive and directly hits the microswitch The limit protrusion 9 for being limited to the active shrapnel 7, institute are arranged on the pedestal 1 in the utility model for ontology 2 It states limit protrusion 9 and is located at the active shrapnel 7 and described between spring plate 8.

The distance between the shaft 5 and the microswitch are less than between the limit protrusion 9 and the microswitch Distance, i.e., with the U-shaped interconnecting piece for installation site on the pedestal 1, the limit protrusion 9 is closer to described Two element 200.

The active shrapnel 7 includes the first shrapnel 71, and first shrapnel 71 is connect with the U-shaped interconnecting piece Second shrapnel 72；First shrapnel 71 is relative to second shrapnel, 72 angled inclination.First shrapnel 71 with Angle between second shrapnel 72 is obtuse angle, preferably, the folder between first shrapnel 71 and second shrapnel 72 Angle is 135 °, to prevent the depth of the first element 100 described dynamic there are that can not be pushed from spring plate 8 described in when mismachining tolerance Make reed 3 to pressing.

When initial, the angle between spring plate 8 and the U-shaped interconnecting piece be less than second shrapnel 72 with it is described Angle between U-shaped interconnecting piece.Preferably, when initial, it is described from spring plate 8 perpendicular to the connecting plate 63, the connecting plate Angle between 63 and second shrapnel 72 is 125 °, and first shrapnel 71 is parallel to the pedestal 1 so that described second It when element 200 is close to the first element 100, can be in contact with first shrapnel 71, be pushed in the second element 200 First shrapnel 71 is to the microswitch ontology 2 during, and the driving wheel 4 is by the pushing away from spring plate 8 Power is rolled from spring plate 8 far from 63 one end of the connecting plate along described from spring plate 8 to described, while the driving wheel 4 drives The dynamic action reed 3 presses；In the utility model select the microswitch ontology 2 with the driving wheel 4, be because, If selecting the microswitch without the driving wheel 4, the U-shaped interconnecting piece and the shaft 5 just need from microswitch compared with It is close can just make it is described contacted from spring plate 8 with reed 3 is acted, along with it is described rotated from spring plate 8 when the distance that generates, can make The changeover mechanism is whole excessively close away from microswitch, it is possible to create the interference to microswitch work.It is revolved in the U-shaped interconnecting piece During turning, the first element 100 is become and first shrapnel 71 and described second from being contacted with first shrapnel 71 Junction contact between shrapnel 72.

Further, the length of first shrapnel 71 is less than the length of second shrapnel 72, and first shrapnel 71 length is more than the 2/3 of 72 length of the second shrapnel.The junction of first shrapnel 71 and second shrapnel 72 is Circular arc chamfering, the quadrangle from spring plate 8 are circular arc chamfering.It is described to be more than first shrapnel from the length of spring plate 8 71 with the sum of the length of second shrapnel 72, with ensure it is described always can be with the drive in moving process from spring plate 8 Driving wheel 4 contacts, and avoid the depth error because of the first element 100 cause described in from spring plate 8 towards the microswitch Since length is not enough detached from the driving wheel 4 in 2 rotation process of ontology.
