Abstract
The utility model relates to a vertical pulling type miniature switch with a single way contact switch, which is characterized in that stators are arranged on both sides of a base; a spring piece is arranged between the two stators, and has a slight radian; the top of the spring piece is connected with a rotor moving plate, a shifting fork and a shaft respectively. The utility model can be used for pressure meters and pressure thermometers.
Description
This practical appliance switch field that relates to specifically belongs to vertical pulling type and is in the microswitch of stirring a kind of one way of connecting or closing, as required can be respectively with manometric spacing, warning or emergency stop valve trip occasion.
Present microswitch, widely-used in every field, but the microswitch volume is bigger, driving torque is also bigger simultaneously, be particularly useful on the pressure gauge, when needing some microswitches to set several set points, then need several that microswitch stack pressure is finished, therefore can not satisfy the appropriate design in the use.
The purpose of this utility model provides a kind of vertical pulling type contact and opens or closes and be the form of stirring, the contact of switch is an one way simultaneously, there is not back fork, in the use of pressure-type thermometer, when several open or close a kind of vertical pulling type dial type one way microswitch that the pressure that does not need to apply stack is finished required set point.
For finishing the technical scheme that above-mentioned purpose is finished: base is set in the housing, left stator and right stator are set on the base, spring leaf is set between two stators slightly has a radian, above-mentioned spring leaf upper end connects moving plate, fork and axle respectively.
Give fork as a power, then spring leaf contacts with the stator of a side, give shift fork as an opposite power, then spring leaf contacts with the stator of opposite side, finishes the action of connecting or closing, in the process of finishing, do not need to revolve again continuously to add any power, can not produce simultaneously one again and return fork power, and, be particularly useful for Pressure gauge or pressure-type thermometer because the straight vertical volume of switch that makes is little.
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings.
Fig. 1 is a structure chart of the present utility model.
According to shown in Figure 1, be provided with between left stator 2 and right stator 8, two stators in two sides of the base of housing spring leaf 3 is set, the upper end of spring leaf 3 is connected and fixed moving plate 4, shift fork 7 and axle 6 respectively, spring leaf one end slightly has a radian, is convenient to a spring leaf left side or the right reliability that contacts with stator.Left side stator 2, an end of right stator 8, spring leaf 3 is connected with lead-out wire by solder joint, cover plate 5 is set at last finishes global switch.
Claims (2)
1, a kind of by housing, the vertical pulling type dial type one way microswitch that base, stator and moving plate are formed, it is characterized in that being provided with on the base (1) left stator (2) and right stator (8), spring leaf (3) is set between two stators, and the upper end of spring leaf (3) connects moving plate (4), shift fork (7) and axle (6) respectively.
2, vertical pulling type dial type one way microswitch according to claim 1 is characterized in that spring leaf (3) slightly has a radian.
