Abstract
The utility model relates to a pointer-type toggling microswitch which is used for a pressure meter or a temperature meter. The utility model is characterized in that a cam is arranged at one side of the microswitch, a left shifting fork and a right shifting fork are respectively arranged at the upper end of the cam, and a rotating shaft is arranged on the cam. The cam and the reed of the microswitch are contacted with each other, so the one-way opening or the one-way closing of the utility model can be finished. The utility model has the advantage of simple manufacturing process. When the utility model is used for the pressure meter or the temperature meter, the strong visualizability can be realized, and the set value of the utility model can have same position with the scale value of the meter; thereby, the setting error of the meter is eliminated.
Description
The utility model relates to the appliance switch field, belongs to specifically to adopt to stir a kind of single pass microswitch of connecting or closing, and can be widely used in the occasions such as spacing alarm, emergency stop valve trip of Pressure gauge and thermometric instrument.
Present sensitive switch is extensive use of in every field, but this type of general sensitive switch is when being applied to pointer instrument, need complicated transmission mechanism to realize action, when such instrument needs some microswitches to set several set points simultaneously, then need several pressure to finish to the microswitch stack, therefore, can not satisfy appropriate design in the use.Once stirred the one way microswitch by a kind of vertical pulling type, though it can overcome the stack pressure of several switches in the instrument use, technological requirement is strong especially, and it is very difficult to carry out quality control, can't overcome human factor.
The purpose of this utility model provides a kind of switch, production technology is simple, need not to overcome artificial factor, especially in the use of curved scale instrument, the setting of some points, a kind of pointer-type that does not need several switch stack pressure to finish is stirred the type sensitive switch.
For finishing the technical scheme that above-mentioned purpose is taked: the side at existing sensitive switch is established cam, the cam upper end is established left shift fork and right shift fork respectively, cam is established rotating shaft, the cam lower end is established two male and fomale(M﹠F)s and is in contact with one another with the switch reed, angle between two male and fomale(M﹠F)s of cam is less than 120 °, greater than 60 °.
The utility model manufacturing process is simple, produce in batches and carry out quality control easily, can be widely used in pointer instrument, can be set directly on the dial, intuitive is strong, the set point that overcomes the pressure type temperature simultaneously can not be arranged on the shortcoming on the same indicating graduation dish, does not therefore deposit the error of set point and actual indicated value, finishes synthermal demonstration.
The utility model is executed example and is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structure chart.
According to shown in Figure 1, one side of sensitive switch 7 is established cam 4, cam 4 upper ends are established left shift fork 1 and right shift fork 3 respectively, finish and stir shift fork by being arranged on driving lever 2 on the instrument between two shift forks, reach the purpose that opens or closes, cam 4 is established rotating shaft 5, make cam rotation, two male and female faces are established in cam 4 lower ends, two male and fomale(M﹠F)s and sensitive switch reed 6 are in contact with one another, angle β between above-mentioned two male and fomale(M﹠F)s is less than 120 °, greater than 60 °, can guarantee that the driving lever 2 on the instrument is finished opening or closing of control switch synchronously with moving of curved scale pointer.
