Abstract
The utility model provides a weak-current-controlled strong current switch including a strong current control circuit, a relay, and a switch panel. A switch control circuit is arranged behind the switch panel, the switch control circuit controls the circuit via a one-chip microcomputer, the switch control circuit is connected to the strong current control circuit, and the relay is connected to the switch panel and the strong current switch circuit. When the switch is used, 220-volt AC do not enter into the switch panel to provide a strong guarantee for personal electric shock safety and fire hazard fighting safety, and the power is on when one presses the button of the switch panel once, and the power is off when on presses the button of the switch panel again. An LED indicating lamp indicates the on or off of the switch corresponding to the button. The switch panel can be in various colors to fit with the style of the decorative environment, thus, the switch provided is beautiful and elegant, convenient in use, and reliable in performance.
Description
Technical field
The utility model relates to the electric switch in the electronic applications, is a kind of contactless electric switch, specifically a kind of weak current control forceful electric power switch.
Background technology
Along with the building up, put into effect of water-power plants such as Three Gorges, Xiao Langdi, the enforcement of west-to-east power transmission, China has obtained huge achievement at aspects such as thermal power generation, hydropower, atomic energy generatings.Little area, the power supply etc. of limiting the quantity of become the history in " time immemorial " in China.The household electrical appliance of various big electric currents such as electric fan, air conditioner, electric heater, micro-wave oven, electric cooker, refrigerator colour TV washing machine have also got into thousands upon thousands families, and the power consumption of urban and urual areas of whole country people of all nationalities is high speed development forward just in big strides ...And electricity consumption is safe, convenient, comfortable ... Become people's active demand.Existing household electrical appliance switch structurally has many weak points, exchanges strong point as 220 volts and directly gets into switch panel, can cause the contact safety of the person; Switch has the contact, and open and close moments will arcing, produce battery simultaneously disturbs, produces electricity and ablate, produce contact resistance, produces heat, produces disaster hidden-trouble thereby produce pressure drop; Use is convenient inadequately, serviceable life is short, performance is reliable inadequately.
Summary of the invention
The utility model provides that a kind of novel structure, easy to use, life-span are long, easy access and widely used weak current control forceful electric power switch.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
The described a kind of weak current control forceful electric power switch of the utility model comprises strong electrical control circuit, relay and switch panel; Behind the said switch panel ON-OFF control circuit is housed, ON-OFF control circuit adopts the microprocessor microcontroller control circuit, and ON-OFF control circuit is connected with the forceful electric power on-off circuit, and relay is connected with ON-OFF control circuit, forceful electric power on-off circuit.
The input of the ON-OFF control circuit described in the utility model is connected with keyswitch, and the output of ON-OFF control circuit is connected with the forceful electric power on-off circuit.ON-OFF control circuit is provided with LED switch key status displays spare, and connects the corresponding switch button respectively.Switch panel adopts film big key shape switch panel.
The beneficial effect of the utility model is: 220 volts of alternating currents do not get into switch panel, can be personal electric shock safety and fire security against fire strong assurance is provided, and the switch panel button is pressed once to opening, and press once for closing again.LED light in order to indicate this button opening or closing inductive switch.Switch panel can use shades of colour to cooperate elegant in appearance, easy to use, the dependable performance of style of decorative environment.
