Description
Technical field
The present invention relates to electric switch field, more particularly to a kind of microswitch for low-voltage electrical apparatus.
Background technology
Current microswitch is widely used in various high, medium and low voltage electric appliance loads, but is led in the low-load of low-voltage electrical apparatus
In domain also use traditional reed-type contact switching mechanism (as illustrated in fig. 1 and 2), the switch include shift knob 1, reed 2,
Movable contact spring 3, moves contravention 4, driver blade 5, switch cover plate 26, switch base 7, switch movable contact point 8, auxiliary terminal 9, switch stationary contact
Point 10, static touching terminal 11.Such a construction of switch is relatively complicated, and assembling procedure is also comparatively laborious, and manufacturing cost is also higher.
The content of the invention
For the problems of the prior art, the present invention provides a kind of microswitch, machinery and the electricity of microswitch of the present invention
Airway dysfunction is identical with current switch, but structure is significantly simple.
To solve problem above, solution of the invention is a kind of microswitch, including pedestal, button, moved end, is moved
Contact, stationary contact, static terminal, cover plate and rivet, the pedestal is matched with cover plate by rivet to be entrenched togather, the pedestal with
Cover plate is internally provided with corresponding cavity to accommodate the button set gradually from top to bottom, moved end and static terminal, the moved end
The sub position corresponding with the static terminal is provided with movable contact and stationary contact, and button lower end is connected with moved end, button pressed downwards
When, due to moved end and button connects, moved end is also moved downward, and the static terminal is fixedly installed on moved end son lower section, moved end
After son one section of distance for setting in advance of motion, the movable contact of the sub and described static terminal opposite position setting in the moved end and quiet
Contact and then conducting switching circuitry, release button move, make push-button reset upwards by the sub bounce of itself in moved end,
The sub movable contact set with the static terminal opposite position in the moved end and stationary contact separate and then disconnect switching circuitry.
As an improvement, the sub position corresponding with static terminal left end in the moved end is provided with movable contact and stationary contact
Point, the moved end is sub parallel with the right-hand member of the static terminal and protrudes from the segment length of pedestal one.
From the above, it can be seen that the new construction microswitch of the present invention is in the case of said function is played, switch knot
Structure is simpler, easy to assembly, and cost has more economy.

Embodiment
With reference to Fig. 3 and Fig. 4, first specific embodiment of the present invention, but the not claim to the present invention are described in detail
Do any restriction.
As shown in Figure 3 and Figure 4, a kind of microswitch, including pedestal 21, button 22, moved end 23, movable contact 241, stationary contact
Point 242, static terminal 25, cover plate 26 and rivet 27, pedestal 21 is matched by rivet 27 with cover plate 26 and is entrenched togather, pedestal 21 and
Cover plate 26 is internally provided with corresponding cavity to accommodate the button 22 set gradually from top to bottom, moved end 23 and static terminal 25,
Moved end 23 and the corresponding position of static terminal 25 are provided with movable contact 241 and stationary contact 242, the lower end of button 22 and moved end 23
Connection, when button 22 is pushed, because moved end 23 is connected with button 22, moved end 23 is also moved downward, and static terminal 25 is fixed and set
Put below moved end 23, after the distance that one section of the motion of moved end 23 is set in advance, moved end 23 and static terminal 25 are corresponding
The movable contact 241 and stationary contact 242 that position is set contact and then turn on switching circuitry, release button 22, by moved end 23 certainly
The bounce of body is moved upwards, resets button 22, the He of movable contact 241 that moved end 23 and the opposite position of static terminal 25 are set
Stationary contact 242 separates and then disconnects switching circuitry.
More specifically, the sub position corresponding with static terminal left end in the moved end is provided with movable contact and stationary contact
Point, the moved end is sub parallel with the right-hand member of the static terminal and protrudes from the segment length of pedestal one.
In summary, new construction microswitch of the invention is in the case of said function is played, and construction of switch is simpler, group
Dress is convenient, and cost has more economy.
It is understood that above with respect to the specific descriptions of the present invention, being merely to illustrate the present invention and being not limited to this
Technical scheme described by inventive embodiments, it will be understood by those within the art that, limited not departing from claim
In the case of fixed spirit and scope, the present invention can be modified or equivalent substitution, to reach identical technique effect, but
All within protection scope of the present invention.
