Abstract
The utility model provides a multiple switch controller used for an illumination lamp or other electric appliances. Two switch control lines can be led to any position needed to be provided with a switch according to the need of users. Not matter how many switches are installed, the switch only needs to be connected with the two switch control lines in parallel. The utility model has the advantages of very convenient installation and use, and has the functions of automatic switching off of a lamp after the power failure and invalidation of the switch after the power failure.
Description
The present invention relates to a kind of controller of switches at different places that is used for illuminating lamp or other electrical equipment.
Existing common power switch majority is a single connection plane switch, when being used for to same road illuminating lamp or other electrical equipment control, a switch can only be installed at a place, also two switches can only be installed at two places if adopt ganged switch (claiming tee again), at least to connect three leads between two switches, if when at three places or more than three places same way control switch being installed, existing mains switch can't be realized.In daily life, for electrical equipment illuminating lamp particularly, often need could satisfy the convenient needs that use at many places installation and control switch.As the house at hotel, hostel, for the control of indoor illumination, the bed switch of outdoor switch, cubicle switch and every berth etc. should be installed all in the ideal case, existing simply connected or ganged switch can't meet the demands.
In use have aforesaid problem based on the existing power supply switch, task of the present invention is the simple controller of switches at different places for lighting lamp of a kind of new circuit of design, makes it easy to install, reaches the purpose of electrical equipment many places, same road being set up switch control.
Task of the present invention realizes as follows, accompanying drawing has provided embodiments of the invention, with reference to accompanying drawing, the present invention mainly is made up of two electronic switch BG1 and BG2～3 and two relay J 1 and J2, by the mains switch control electronic switch action that is connected in parallel in the thread switching control, by the operating state of electronic switch control relay.The automatic power switch of load (illuminating lamp or other electrical equipment) and this control circuit is undertaken in the contact of J1, and the automatic conversion of control line switching function is undertaken in the contact of J2.
Thread switching control of the present invention has only two, wiring is simple, can be according to user's needs, many mains switches are installed to same illuminating lamp or the convenient control of other electrical equipment in many places, no matter what mains switches are installed only needs switch is attempted by on these two thread switching controls and gets final product, after any switch is turned on light, can turn off the light with any switch.The present invention's not power consumption when turning off the light, power consumption is less than 2 watts when turning on light, and have and turn off the light automatically after the power failure and have a power failure the invalid function of back switch, power savings is good, safe and reliable, the light control of the unit of being widely used in, family's multilayer stair light, corridor lamp, street lamp, room, parlor, toilet is specially adapted to hotel, guest room, hotel and worker, collective of students dormitory.
Fig. 1 is an appearance structure schematic diagram of the present invention;
Fig. 2 is circuit theory diagrams of the present invention.
Below in conjunction with accompanying drawing the present invention is described in detail.
With reference to Fig. 1, the present invention is made up of plastic casing, the printed circuit board (PCB) that is welded with components and parts, the indicating device of turning on light, the plastic casing bottom surface is equipped with and installs and fixes the hole, can adorn solid on wall, the side is equipped with totally 6 of power input, load output and switch control ends, wherein 3,4 terminals are power input, connect～220V by power line; 1,2 terminals are the load output, connect illuminating lamp ZD or other electrical equipment by the load output line; 5,6 terminals are the switch control end, can and meet many mains switch AN according to user's needs by thread switching control.The indicating device XD that turns on light is installed in the box front, represents when bright to can be used as light monitor by switch connection, if XD is bright and ZD does not work, illustrates that ZD burns out or electric wire opens circuit etc., can shorten the repair time.Mains switch AN adopts push-button switch, can not be with common pulling switch or toggle switch.
With reference to Fig. 2, the present invention forms power automatic switch circuit by triode BG1, relay J 1, resistance R 1, relay contact J2-1, is made of the switching function automatic switching circuit that postpones control triode BG2 and BG3, relay J 2, capacitor C 2 and resistance R 2～R4.One end of AC power and the elementary winding of power transformer T and load one end link, the other end of AC power is succeeded appliance contact J1-1 and mains switch AN, behind AN, connect the armature contact of J2-1, link by the normally-closed contact of J2-1 and elementary winding, relay contact J1-1 and the load other end of T; The normally opened contact of J2-1 connects the base stage of BG1, and the output of T secondary winding provides the dc supply of control circuit behind D1 and C1 rectifying and wave-filtering.
After energized, do not press mains switch AN before, power transformer T non-transformer output, control circuit does not have dc supply does not work, load is in off state.When click arbitrary of AN(AN1～ANn with hand) moment, to T and electric, illuminating lamp ZD is bright through the normally-closed contact (position as shown in the figure) of AN, J2-1 for AC power, BG1 obtains forward bias and conducting through R1 simultaneously, the J1 adhesive, contact J1-1 closure, XD is bright.Even no longer press AN this moment, because the closure of J1-1, T still switches on, and BG1 is operate as normal still, and it is shinny that ZD keeps, and load is in on-state.
Owing to be generally less than 20ms the pickup time of relay, and that hand is pressed the time of mains switch is longer, generally greater than 100ms, so the switching function automatic switching circuit of being made up of BG2～3 and J2 must postpone adhesive, the contact that promptly must treat mains switch AN is left back J2 and is just allowed adhesive, otherwise J1 and J2 adhesive and release repeatedly voluntarily makes the control circuit cisco unity malfunction.Delay of the present invention is about 400～800ms pickup time, forms delay circuit by R2, R3, C2, and R3 is again the bleeder resistance of C2.After BG1 work, through the delay of 400～800ms, BG2～3 conducting work, the J2 adhesive, contact J2-1 conversion, this moment, mains switch AN was automatically changeb to the function of power cutoff from the function of energized.When turning off the light, click AN with hand, BG1 base stage and ground short circuit lose bias voltage, and BG1 ends, and J1 discharges, and contact J1-1 opens, and disconnect AC power, and this moment, ZD, XD extinguished, and load is turn-offed.Because the capacity of C1 and C2 is bigger, BG2～3 bias voltages can not disappear immediately, end so BG2～3 will postpone about 200～500ms, and J2 discharges, control circuit returns to initial state, when having avoided hand also not decontrol AN and control circuit is converted to the error condition of turning on light again.
Be the excessive influence to delay circuit of the base stage bias current that prevents BG2, the multiple tube form is adopted in BG2～3, makes the bias current of BG2 radix less than 50uA.J1, J2 adopt small-sized high sensitive relay, can choose different model according to bearing power.
