Technical field
It the utility model is related to the research and development of oil instrument and manufacturing technology field, especially a kind of electronics of logic-based circuit
Switch.
Background technology
Common switch such as switch on wall, the blade type machinery stop switches that sub switch belongs to physical contact are turned round, passed through
Mechanical moving part control blade type contact is contacted or disconnected with physical contact, so as to the conducting or open circuit of control circuit.This type is opened
The moving part and contact part of pass generally contact with external environment, are susceptible to the influence of environmental factor, are such as used in open-air atmosphere
When, the erosion of overcast and rainy wet environment is susceptible to, is destroyed switching function, while has larger potential safety hazard.
The content of the invention
The technical problems to be solved in the utility model be to provide one kind can open-air atmosphere use, by wet weather corrode,
The electronic switch for the logic-based circuit that switching mechanism is isolated from the outside completely.
In order to solve the above-mentioned technical problem, the utility model includes Piezoelectric switches and logic control circuit；The piezoelectricity is opened
Piezoelectric signal voltage can be produced dependent on the operation to piezo-electric effect, pressing operation face by closing, by inside amplification and according to condition
Short electric pulse is provided, often pressed once, produces moment " contact closure " pulse between a 10-1000ms；The logic control
Circuit processed includes logical device, driving element and the part discrete component of welding on circuit boards, and the Piezoelectric switches are by leading
Line is connected with logical device, and the logical device often operates once, its state invert once, and by driving element realize open or
Close once.
The logical device is logic gates or d type flip flop or JK flip-flop.
The beneficial effects of the utility model are：Each component in the utility model is easily obtained, and is easily assembled to, and is easy to tie up
Shield, it is simple in construction, facilitate staff to operate, it is achieved thereby that the safety and effectiveness of switch.
Brief description of the drawings
Fig. 1 is the electric composition schematic diagram of the electronic switch of the utility model logic-based circuit.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Referring to Fig. 1, the electronic switch of logic-based circuit of the present utility model includes Piezoelectric switches 1, logic control circuit 2
And some wires.
The Piezoelectric switches 1 are a kind of electronic components of no-movable part, and reliability is high and is not influenceed by ESD, especially suitable
Together in outdoor, low prison safety applications；Operating temperature range is wide, has resistant function to oily and many compounds；The Piezoelectric switches 1
Dependent on the operation to piezo-electric effect, pressing operation face can produce piezoelectric signal voltage, amplify by inside and carried according to condition
For short electric pulse, often press once, produce moment " contact closure " pulse between a 10-1000ms.
The logic control circuit 2 is execution unit, and by logical device 3, (logic gates or d type flip flop or JK trigger
Device etc.), driving element 4 and part discrete component 5 form, it is welded to turn into circuit board assembly.Logical device 3 often operates once,
Its state is inverted once, and on or off is realized once by driving element 4；The maximum permissible voltage and electric current of electronic switch and driving
The selection of device is relevant, can reach 1000V/20A or bigger.During welding, solder joint exposed position is subject to appropriate insulation protection,
And suitably strengthen the intensity of wiring.
When the utility model device uses：
Piezoelectric switches 1 are installed on panel first, installation interface pays attention to sealing waterproof；Logic control circuit 2 is installed
On the inside of panel, it is connected by wire with Piezoelectric switches 1, and electrical equipment is connected by wire.An in use, piezoelectricity of pressing
Switch 1, equipment will be switched on (shut-off) power supply；If pressing Piezoelectric switches 1 again, equipment will be off (connection) power supply.With this
Analogize.Because Piezoelectric switches 1 are an airtight waterproof devices, it is installed on panel, protects the logic control circuit 2 of inside to perform
Part, it is achieved thereby that the purpose of waterproof electronic switch.
In summary, content of the present utility model is not limited in the above embodiments, and those skilled in the art can
To propose other embodiments within technological guidance's thought of the present utility model, but these embodiments are included in this practicality newly
Within the scope of type.
