As Fig. 1, shown in Figure 2, the utility model contact type energy-saving switch is made of switch box body 3 and switch panel 2, switch panel 2 is the plastic plate of whole zero-clearance, its inboard sticks piezoelectricity singing piece HTD, be 1 among Fig. 2, electronic circuit in the switch box body 3 is by the monostable time delay circuit, switching circuit, spike harmonic wave rectification and indicating circuit, power rectifier circuit and should wrap signal acquisition circuit and form, the monostable time delay circuit is by time base IC integrated package NE555 and resistance R 4, capacitor C 2 constitutes, piezoelectricity singing piece HTD connects pin 2 and the ground connection of integrated package NE555, resistance R 1, be connected between the two poles behind R2 and the R3 polyphone, the pin 2 of integrated package NE555 also with resistance R 1, R2 joins.Switching circuit is made up of resistance R 7, diode D2, voltage-stabiliser tube ZD3 and unidirectional thyristor VS, be connected on after diode D2 and the voltage-stabiliser tube ZD3 series connection between the pin 3 of the trigger electrode of unidirectional thyristor VS and integrated package NE555, the anode of voltage-stabiliser tube ZD3 connects the trigger electrode of VS, the negative electrode of diode D2 connects the output pin 3 of NE555, be connected to resistance R 7 at diode D2 and voltage-stabiliser tube ZD3 joint, the other end of resistance R 7 and the output that is connected to power rectifier circuit after the anode of unidirectional thyristor VS links to each other; Spike harmonic wave rectification and indicating circuit be by capacitor C 3, C4, resistance R 5, R6, and diode D1 and LED are formed; And the emergency signal Acquisition Circuit is made up of with ZD2 and capacitor C 1 voltage-stabiliser tube ZD1, after voltage-stabiliser tube ZD1, the ZD2 differential concatenation, is connected to the junction of resistance R 2 and R3 by capacitor C 1, and emergency signal is by the anode input of voltage-stabiliser tube ZD1.Power rectifier circuit is made up of diode D3 to D6.The luminous component of LED is near the switch panel inner surface.The power input of power rectifier circuit is serially connected with in the illuminating line by binding post 5 and illuminating lamp, need not distinguish phase line and zero line.And from the emergent end line 4 that the anode of the voltage-stabiliser tube ZD1 of emergency signal Acquisition Circuit is drawn, can connect together by emergent plug-in strip control with the emergent end of similar other switch.The emergency power supply line can be any phase line in the lighting power supply system, also can be zero line or direct ground connection.
The operation principle of the utility model contact type energy-saving switch is: insert 220 volts of civil powers after this switch is connected with illuminating lamp, alternating current carries out bridge rectifier through power rectifier circuit, form pulsating direct current, put on the unidirectional thyristor VS, and through resistance R 6 and R5 step-down, the LED of flowing through makes its luminous position with the expression power down switch.Again by capacitor C 3 filtering, form level and smooth low-voltage DC, power to delay circuit, when unmanned touch switch panel, piezoelectricity singing piece HTD no current produces, because of resistance R 1, R2 and R3 series connection, make pin 2 current potentials of integrated package NE555 be higher than 1/3 DC power supply voltage, at this moment, the monostable circuit that is made of integrated package NE555 etc. is in stable state, the output pin 3 of integrated package NE555 is in electronegative potential, and the Rectified alternating current that power rectifier circuit provides puts on diode D2 anode through resistance R 7, because the output pin 3 of the integrated package NE555 that links to each other with diode D2 negative electrode is in electronegative potential, diode D2 conducting, draw the current potential of diode D2 and voltage-stabiliser tube ZD3 connecting place very low, not conducting of voltage-stabiliser tube ZD3, unidirectional thyristor VS can not get trigger current and is in off state, illuminating lamp does not work, at this moment, power down switch two power input voltages are very high, near 220 volts.And when hand by or when knocking power down switch panel 2, active force reaches on the piezoelectricity singing piece 1 by insulating panel, making piezoelectricity singing piece 1 is that HTD produces electric current, thereby pin 2 current potentials of integrated package NE555 are pulled down to below 1/3 of DC power supply voltage, trigger integrated package NE555 delay circuit, make it enter temporary stable state, integrated package NE555 output pin 3 becomes high potential by electronegative potential, diode D2 instead becomes not conducting partially, the anode potential of diode D2 is not subjected to the influence of integrated package NE555, can voltage-stabiliser tube ZD3 cathode potential be raise gradually along with the pulsating direct current that provides through resistance R 7, when pulsating dc voltage is higher than voltage-stabiliser tube ZD3 puncture voltage, voltage-stabiliser tube ZD3 begins conducting, the trigger electrode of unidirectional thyristor VS begins to obtain trigger current, this electric current increases with the rising of pulsating dc voltage, arrive to a certain degree when pulse dc high voltage is high, offer unidirectional thyristor VS trigger electrode through voltage-stabiliser tube ZD3, when the electric current of trigger electrode reaches the required trigger current value of unidirectional thyristor VS conducting, unidirectional thyristor VS conducting, power supply forms path by diode D3 to D6 and unidirectional thyristor VS, provide electric current to illuminating lamp, make illuminating lamp luminous.After the unidirectional thyristor VS conducting, its anode potential sharply descends, thereby on anode, form a spike, the high order harmonic component of this spike can be carried out harmonic wave rectification by capacitor C4 and diode D1, LED and capacitor C 3, to the delay circuit power supply, LED can stop the reverse release of direct current supply voltage.The both end voltage of power down switch is very low under the illumination lamp ignition state, but by spike harmonic wave rectification circuit, can guarantee the steady direct current supply of delay circuit.After voltage-stabiliser tube NE555 enters temporary stable state, resistance R 4 is to capacitor C 2 chargings, along with electric charge accumulation on the capacitor C 2, the pin 6 of integrated package NE555, pin 7 current potentials raise gradually, when current potential is elevated to place value, the quick backspace stable state of single stabilization delay circuit, the pin 3 of integrated package NE555 is reduced to electronegative potential fast by high potential, diode D2 recovers conducting, and voltage-stabiliser tube ZD3 turn-offs, and unidirectional thyristor VS becomes off state by conducting, the current path of blocking-up illuminating lamp, light extinguishes, and alternating supply voltage all is added to switch ends again, and the pulsating direct current after rectification is powered to delay circuit through diode R6 and R5 step-down.
When emergencies such as breaking out of fire, emergent plug-in strip closes, make the emergency power supply signal send into the emergent end of power down switch through emergent plug-in strip, enter the pin 2 of integrated package NE555 again through voltage-stabiliser tube ZD1, ZD2 and capacitor C 1, resistance R 2, remove to trigger integrated package NE555, make integrated package NE555 enter temporary stable state, make illumination lamp ignition.Because emergent plug-in strip is closed, make emergency signal continue to be added on the emergent end of power down switch, force the integrated package NE555 in the power down switch to be in temporary stable state muchly, thereby reach the emergent purpose kept burning day and night of illuminating lamp.After the emergency rating, draw back emergent plug-in strip, power down switch recovers time-delay from putting out function.Therefore, the utility model power down switch is specially adapted to the public illumination of skyscraper.
