Description
Technical field
This utility model relates to a kind of switch, be specifically related to a kind of by pressing realize conducting by compressing switch.
Background technology
At present, on the vehicles such as some long-distance buses, motor-car or aircraft standing have be easy to people's Heat preservation food
Heated base, described heated base is provided with by compressing switch, people press and described press the button compressed switch, and will make heating
Base keeps conducting, and completes the Heat preservation to food, and after having heated, people unclamp and press the button compressed switch, and described press
Compress switch and will reset, and make heated base disconnect electrical connection.But to comprise parts by compressing switch more due to traditional, and structure is multiple
Miscellaneous, therefore assemble inconvenience, and the problem of loose contact often occurs after assembling, additionally, traditional by compressing switch in use,
If people's pressing is the most excessive, then can directly damage the conductive component of the inside by pressure, thus cause pressing switch failure.
Summary of the invention
For the deficiencies in the prior art, this utility model provide a kind of simple in construction, easy to assembly, contact solid and reliable
By compressing switch.
For achieving the above object, this utility model provides a kind of by compressing switch, and includes housing, button, spring, elasticity
Contact chip, stitch plate, the front end face of housing is provided with opening, and described stitch plate is detachably secured on housing and constitutes housing
The closing of upper shed, the upper surface of housing offers through hole, and described button includes the connection post being located in described through hole,
The upper end connection connecting post has button head, and the lower end connection connecting post has square block, and the cross section of button head and square block is equal
More than the cross section of through hole, described square block be provided with downward through cavity, described spring is installed in cavity, spring
Upper end abut with cavity top, the lower end of spring is connected on the bottom surface of housing, and described elastic contact chip is detachably fixed
On the front end face of square block, the two ends up and down of elastic contact chip are also arranged with the contact feet extended that turns forward, and described
The outer end of contact feet takes the shape of the letter U and bends inwards, and is pressed on stitch plate, and stitch plate is placed with can be with contact feet outer end pair
Should be formed and conduct or the stitch of disjunction cooperation, the bottom welding of stitch has the fast connecting terminal of a pair band wire.
The beneficial effects of the utility model are: use said structure, and people, by pressing button, will make button with elasticity
Contact chip overcomes acting force of the spring to move down, after the downward sliding of contact feet on elastic contact chip by with the stitch on stitch plate
Conduct, thus realize electrical connection；Release button, button is by self-return under the action of the spring, on elastic contact chip
Contact feet by with the stitch disjunction on stitch plate, thus disconnect electrical connection.Due to this utility model, to comprise parts less, because of
This simple in construction, easy to assembly, meanwhile, because described contact feet is to tilt to extend out from elastic contact chip, and described contact
The outer end of foot takes the shape of the letter U the setting that bends inwards, and the most described contact feet is pressed on stitch plate, can have certain elastic force,
Under the effect of this elastic force, contact feet can be made to be held against state with stitch plate all the time when sliding upper and lower along stitch plate,
So that can remain solid and reliable by the contact compressed switch.Additionally, because described elastic contact chip and stitch plate are respectively provided with
In the front of button, therefore people are when pressing button, even if the most excessive, are also not result in pressing switch failure.
This utility model can be further arranged to described housing and be provided with the first clamping projection, right on described stitch plate
Should be provided with and constitute, with the first clamping projection, the first blocked hole that clamping fastens.By above-mentioned setting, stitch plate can be made easily may be used
Remove and install and be fixed on housing.
This utility model may further be provided and is provided with the second clamping projection, described elastic connecting for described square block
It is correspondingly provided with on contact and constitutes, with the second clamping projection, the second blocked hole that clamping fastens.By above-mentioned setting, elastic connecting can be made
Contact is the most detachably fixed on the square block of button.
This utility model may further be provided as the 3rd clamping projection that also extended back on described housing.By upper
State setting, contribute to housing clamping and install.
